Benefits Of Using Javascript

JavaScript is undoubtedly a very versatile and is one of the easiest languages that can be used in a website to extend the functionalities. JavaScript Development helps in many was like data processing and calculation, visual effects that can be applied on-screen and a lot of others. You can also use the third party scripts to extend the functionalities. In this article, we will see the advantages of using Java Scripts.

Want to fiddle around with Javascript in a production environment? First, you’ll need web hosting. Get hosting with a price reduction on different hosting plans here.

An easy language

More than anything JavaScript is a language that is very easy to learn. You can see that the syntax that is followed in the language is very close to English. Since JavaScript uses the DOM model, there are a lot of per defined functionalities. This makes it very easy and to develop entire scrip. It is just like taking a walk in the park.

 It is very fast for the user end

The processing is done within no time, and you can get the result easily because the code is executed on the client side. It does not require the server to process the codes. The bandwidth consumed by JavaScript is also very low as it is not sent back to the user for processing.

 

Extended functionalities

There are a lot of third-party add-ons like Grease Monkeys. These add-ons allow the developers or coders to write snippets. These JavaScript snippets can be executed on the on any of the web pages. It will help to extend the functionality of that particular page. You can use add-ons like Grease monkeys to add a certain feature that you require to a website. You can do it on your own and do not need to depend on others.

No compilation

The JavaScript is interpreted as HTML tags by the browser itself. Hence there is no requirement for a compiler or any compilation process.

Easy to debug

Debugging is the process of eliminating the bugs or errors in the program. Since the syntax of JavaScript is very easy to understand Debugging will be very easy. Unlike other languages, JavaScript takes very less time for the debugging process.

Platform Independent

Any JavaScript can be interpreted easily. All it needs is a browser that is JavaScript enabled. There are also no hardware restrictions. JavaScript code can be run in different kinds of hardware.

Event-Based programming language

In JavaScript whenever a certain event occurs different code segments are executed. This is called event-based programming. To put it is a simple way a particular segment of code is only executed a button is clicked, or the mouse is moved.

Procedural programming capabilities

All the procedural language capabilities that include branching, looping, condition checking and a lot more can be done in JavaScript. It has almost every capability that the user needs.

It is a client-side language

The JavaScript does not require a web server to execute the code. Instead of the server, it is executed in the processor. Hence it saves a lot of bandwidth and web load. Be mindful that a pure javascript site may hurt your search engine optimization efforts. Although, according to S E O-Advantage, google can now crawl websites much more effective if you’re using prerendering tools such as prerender.io.

Making a Mini-Lisp: Introduction to Transpilers

This article is an introduction to Transpilers which is the process of translating one programming language into another. This process may be called compiling, transpiling, or interpreting depending on the nature of the input and output languages. Usually compiling is used to describe the process of translating a higher level language, like Java, into machine language, and traspiling is used to describe the process of translating one higher level language into another higher level language. In this article I will show you how to translate, or “transpile”, one high level language into another high level language. Translating one language into another seems like a daunting task at first, but when you break it up into smaller, more manageable tasks, you will realize it is not so hard.

Our goal in this article is to understand how to make a program that will transpile a made-up language called “Minilisp” into JavaScript. Minilisp is just a very simple version of Lisp, which is a high level programming language famous for its use of parenthesis.

Here’s an example of Minilisp. The code below will give us the answer to the simple math proble 3 + 4 * 2:

(+ 3 (* 4 2))

1
2
3

(+ 3 (* 4 2))

Our transpiler will take this code and translate it into a JavaScript program that does the exact same thing:

add(3, multiply(4, 2));

1
2
3

add(3, multiply(4, 2));

We will also go a little bit beyond this to allow our Minilisp user to compose basic functions into higher level functions. An example of this is combining addition and division to make function that returns the average of two numbers. That would look like this in Minilisp:

(defn average
(x, y)
(/ (+ x y) 2 ))

1
2
3
4
5

(defn average
(x, y)
(/ (+ x y) 2 ))

The code above uses the “defn” function call which takes three parameters. The first parameter is the name of the function, which in this case is “average”. The second parameter to defn defines what kind of parameters the function we are defining will accept, and the third parameter is the code that will be executed when we call our new “average” function. If we read over this code in English it would be something like “I am invoking defn to define a new function called average that takes two parameters x and y and returns the value obtained by adding x and y and then diving the result by two.”

Now that we are familiar with Minilisp, lets start working on our Minilisp transpiler. The first step is to take the process of transpiling Minilisp in Javascript and break it into smaller chunks each of which performs just one step in the overall process. Below is a diagram that shows you how we are going to break up this task. We start with a block of text that contains our Minilisp code and then that code gets passed through a series of intermediate steps before it comes out as functional JavaScript.

Angular 2 for React Developers

Now that Angular 2 is in beta, the time has come for us to drop everything and learn something new, again. The good news is, like React and Angular 1.x, Angular 2 is here to stay for a while so it’s a good investment to become productive with this new framework. React has been on top of the world as of recently, for good reasons, it’s a fantastic approach to building modern web apps. This post is catered to those who are neck-deep in React and what to make an easy transition to Angular 2. This is angular 2 for react developers.

Bootstrapping

Both React and Angular 2 can be used with normal ES5, but most folks use JSX + ES2015 with React and with Angular 2 it’s also recommended to use TypeScript.

> TypeScript is ES2015 + Optional Types

None of those technologies can run natively in any browser, so we must have a build step to compile down to browser ready code. Webpack and/or Gulp are the popular choices for the bundling and building our application code. Once you have your build process, we can bootstrap our app. As far as bootstrapping our first component, things will obviously be different between the two frameworks.

React Developer Survey Results

Survey1 commentReact, Survey

Four months ago I released a survey asking React developers about their community. I did this to gauge the community and compare the findings on how similar they are to another Web Development community, Angular (where the idea for a survey was inspired originally from Jeff Whelpley and PatrickJS). What I found was a lot

Angular 2 Components For AngularJS Developers

Components are the molecules of Angular 2 applications, and we are going to spend a few minutes introducing this new building block. We are going to assume a basic familiarity with Angular 1 and the fundamental mechanisms of the framework. And now time for a brief history lesson!

A Brief History of Angular 1.X Views and Controller

In Angular 1, the prevalent theme was a controller and template pair. As the novelty of sample applications wore off, there was a natural evolution of how views and controllers were approached within an Angular application. People wanted to build complicated things that solved hard problems.

Sample Application Scenario

The initial approach was to build out an HTML template and drop in a controller via ngController. This approach worked as long as we were doing sample applications and to-do lists. Small and limited functionality resulted in a small controller that was easy enough to manage.

Sample Application Meets the Real World Scenario

As our application grew, so did our controller. This eventually became unwieldy, and we needed to find a better way to divide our application up into smaller pieces. There are two dominant approaches to this problem, and each has their own merits. You could break your app up into template-controller pairs with named routes using ui-router, which essentially turned your application into a state machine. Or, you could divide your interface up into self-contained directives that encapsulated the template-controller pair.

Angular Connect 2015: A Highlights Tour

AngularConnect 2015 is over, and what a conference it was! With two tracks of talks, two tracks of Q&A, one track of unconference talks, and countless hallway conversations, it was one of the biggest tech conferences I’ve ever attended. At this point my head is spinning from everything I’ve learned, and it’ll take some time to digest it all.

If there’s one major takeaway I felt this conference had, it’s that the community’s suspicion of Angular 2 has largely subsided. At this point people pretty much know what Angular 2 will look like and how they’ll be able to migrate their apps to it. Most of the discussion – both in the talks and in the hallways – had shifted to all the things we’ll now be able to do with Angular 2: What existing problems it solves, and what completely new things it makes available.

Angular 2 for AngularJS Developers

Now that Angular 2 released beta someone moved our cheese! Let’s put on our running shoes. First off let me start off by saying I have been writing Angular 2 for nearly one year now (actually, since this tweet) and writing AngularJS since the first stable release. I want to share what I quickly discovered in that time. We are going to see that everything’s changed but nothing is different. This is the Angular you have been looking for this is Angular 2 for AngularJS developers.

Terminology
* For this article when I refer to AngularJS I’m speaking about Angular 1.x and Angular as both frameworks
* Keep in mind that ES2015 was previously known as ES6
* TypeScript is simply ES2015 + Optional Types
* A Type is a class

Bootstrapping
Both AngularJS and Angular 2 can be used with normal ES5, but most folks should be using ES2015 with AngularJS and with Angular 2 it is highly recommended to use TypeScript.

It’s worth noting that our browsers today currently varies when it comes to ES2015 features that are implemented. Neither technologies (ES2015 or TypeScript) can run natively in any browser (perhaps TypeScript with Edge browser). We must have a solid build step to transform our code into ES5 for cross platform support. Webpack and/or Gulp are the popular choices for the bundling and building our application code. Once you have your preferred build process we can bootstrap our application. If you’re in a hurry and just wanna get started, check out our Angular 2 Webpack Starter and NG6-starter (AngularJS) on github.

State of Type Script Packages

As a module author and developer, I love TypeScript. It allows me to write, publish and consume 100% type-safe JavaScript. Features like autocompletion, type validation and ES6 features are now part of my typical workflow. I’ve published half a dozen modules on NPM, but no one has ever been able to consume the type definitions from them. Why’s that?

Let’s quickly take a step back. TypeScript includes a creative way for providing the type information of plain JavaScript files. These are .d.ts files, also known as “typings”, which allows non-TypeScript packages to have a .d.ts file written and mirror the runtime JavaScript implementation of that package. This decoupling of the runtime and type compiler is truly elegant, as the TypeScript compiler can output .js and .d.ts files together and it works as if it is all TypeScript. This has two amazing effects:

The greater community can write their own type definitions (.d.ts files) for non-TypeScript packages – which is pretty much every popular library on NPM
It promotes JavaScript as the first class citizen, something the first “compile-to-JS” languages like CoffeeScript failed to do (it promoted – through general availability – the use of things like coffeescript/register at runtime)
To help understand how we, as a community, got here and where we’re going next I’m going to give you a quick history lesson.

The Past
Welcome to the past, the wild west of .d.ts files. A community project called DefinitelyTyped, started by Boris Yankov, is first committed to over three years ago. DefinitelyTyped has evolved 100 times over since the initial inception, but the core premise is to use ambient module declarations that define types for packages in NPM, Bower and the browser.

Create A Simple Reactive Store For Angular

Angular 2 uses observables for many features and has a peer dependency on RxJs for its robust API around observables. The community has adopted a single store approach for dealing with state in modern applications. Let’s build a store for our Angular applications that is both reactive and easy to use with RxJs.

Single store is awesome
We’ll create this store with intentions on it being the only store in our app. By doing this, we can provide a better experience and lower the difficulty of reasoning about state in our app, because all the state is in one place! First we’ll create the provider for the store itself.

export class AppStore {}
Add a subject
Right now our store literally does nothing. We want this store to have a reactive api that we can use in our application. We’re going to create a Subject using RxJs. A subject is perfect for our store because we can multicast to more than one observer. This just means we can setup many listeners. This is going to allow use to subscribe to our store in other components and providers. We need the Subject to always know what the current state is at all times, and when a new observer subscribes, the Subject should provide the observer the current state. Luckily, there is a special Subject for this, a Behavior Subject. Let’s make our store reactive!

import { BehaviorSubject } from ‘rxjs/BehaviorSubject’;

const store = new BehaviorSubject();

export class AppStore {
store = store;
}
Above we created the store outside the class to ensure there will only ever be one instance of the actual store no matter how Angular injects and instantiates the AppStore provider. Now lets set a default value for our store.

import { BehaviorSubject } from ‘rxjs/BehaviorSubject’;

const state = {
user: {},
isLoading: false,
items: []
};

const store = new BehaviorSubject<any>(state);

export class AppStore {
store = store;
}
Subscriptions
At this point, our AppStore is ready to be used in our app! Yea, that’s basically it, surprised? Although we could stop here, we should make it super easy to work with the store in our application.
