The 4 Most Used Programming Languages

The-4-Most-Used-programming-languages_ywf

Nowadays, software developers are in high demand. This makes good developers are hard to find, yet they have the luxury of choosing from more than one job offer. So, what makes a ‘good developer’? A good developer should at least know some of the following skills. If you wish to become a good web developer, make sure you have mastered below skills.

  1. C#

C# is designed to be relatively easy and straightforward which makes it incredibly popular among developers and employers alike. C# is primarily used to develop web, mobile and enterprise applications while supporting imperative, functional and object-oriented paradigms.

Above all, there are two reasons why C# developers are terribly needed. First, it is because of its flexibility and usability. Second, it is firstly developed by Microsoft to build apps on the Microsoft platform.  So, it surely will fit in most common Microsoft IT infrastructure, which many companies have set in their system.

  1. PHP

PHP is another popular option; it’s an open source, server-side scripting language. In fact, PHP have powered millions of websites across the world, including high-profile sites such as Facebook and Wikipedia. Moreover, PHP is a language that is so popular that is used extensively in WordPress.

Over the years, PHP’s popularity has increased and there are no signs that this demand will slow down. That is why many companies will offer high salary for getting a good PHP talent.

  1. Java

Java is one of the oldest language programs that are favorable among developers. Because it is relatively easy and versatile, Java has become an attractive proposition for corporations and developers. Besides, it has many users, many existing applications and such a vast ecosystem.

Furthermore, Java is a stable language which makes the job market shows sustained hunger for developers in this field.

  1. JavaScript

Another language program that has gained everlasting popularity is JavaScript. It’s a versatile, object-orientated programming language that is built into most major browsers, including Firefox and Safari. Even though, JavaScript has been around for years but it can manage to hold its own against the existence of so many new languages. In fact, many regard it as one of the need –to-know language to help further a career. With so many developers have acquired this language, you need to double your work to stand out from the crowd.

3 JavaScript Libraries to Look Up for in 2017

3-javascript-libraries-to-look-up-for-in-2017

For some web developers, JavaScript’s ecosystem can be fatigue. Especially this year where there is a lot of tooling and configuring is required. So, to make your work easier, we submit a list of 3 generic libraries/frameworks for front-end development.

Vue.js

If you haven’t put any attention on Vue.js before, now you have to keep your eyes on. It is a tiny JavaScript framework which seems to primarily focus on views and give you only a handful of tools to regulate data for those views. Moreover, Vue.js is also good for a change as it doesn’t get stuffed with programming design pattern and limitations.

There are two types of Vue.js. A stand-alone version that includes the template compiler and the runtime version that doesn’t. You can see its simplicity, through an example of a component that shows a message and brings interactivity to a button to reverse the message.

<div id="app">
  <p>{{ message }}</p>
  <button v-on:click="reverseMessage">Reverse Message</button>
</div>
import Vue from 'vue'

new Vue({
  el: '#app',
  data: {
    message: 'Hello World!',
  },
  methods: {
    reverseMessage: function () {
      const reversedMessage = this.message
        .split('')
        .reverse()
        .join('');

      this.message = reversedMessage;
    },
  },
});

Don’t you worry about the existence of other plugins, as you still can find them on Vue.js. In fact, several guides are available to use there. This framework will be suitable for you, especially if you wish to have productive fast. It also scales well as the project grows.

Svelte

Svelte must be the latest JavaScript Libraries as it has been released in mid-November 2016. At some point, it may looks similar to Vue.js, but leaves a smaller footprint. “Traditional” frameworks need runtime code to define and execute modules; keeps state, update the views and do whatever frameworks do. Moreover, with Svelte you can dissolve into clean JavaScript code as of you didn’t use a framework at all. The big advantages that you can get is that its file size.

Svelte has plugins so you can compile the source code using Webpack, Browserify, Rollup or Gulp.

You can use the below example of creating the Vue.js example with Svelte as a comparison:

<p>{{ message }}</p>
<button on:click="reverseMessage()">Reverse Message</button>

<script>
export default {
  data () {
    return {
      message: 'Hello World!',
    }
  },
  methods: {
    reverseMessage () {
      const reversedMessage = this.get('message')
          .split('')
          .reverse()
          .join('');

      this.set({
        message: reversedMessage,
      });
    }
  }
};
</script>

The very same module created with Vue.js produces a 7kb bundle. Svelte produces a 2kb file.

In terms of performance, Svelte competes with Inferno. This makes Svelte becomes a good choice if you care about your application’s footprint. At the time of writing, Svelte either doesn’t have its plugin system documented, or doesn’t have one at all. The TODO indicates that Svelte will support plugins and might have an API to hook into the framework.

The compatibility of the compiled code depends on your build workflow stack, so it’s hard to say what its default compatibility is. Technically you should be able to achieve pre-ES% support by including ES5 shims.

To conditionally load and invoke modules, Conditioner.js is one of the good choices. The difference from other module loaders is that conditioner.js allows you define conditions under which to load and/or show a module. This results in reducing loading time and saving bandwidth.

However, you better already have functional components in place that are enhanced with a given JavaScript module. How those modules are defined is entirely up to you. You could even make it load modules from your favorite framework.

To get started, you can install it via npm: npm install conditioner-js.

The demo is unlike previous ones to better illustrate Conditioner.js’ features. Imagine we wish to show the time remaining to an event. A module is shown like this:

import moment from 'moment';

export default class RelativeTime {
  /**
   * Enhance given element to show relative time.
   * @param {HTMLElement} element - The element to enhance.
   */
  constructor(element) {
    this.startTime = moment(element.datetime);

    // Update every second
    setInterval(() => this.update(), 1000);
    this.update();
  }

  /**
   * Update displayed relative time.
   */
  update() {
    element.innerHTML = this.startDate.toNow();
  }
}

It is so simple to initialize the module:

<time datetime="2017-01-01" data-module="ui/RelativeTime">2017</time>

Conditioner will then load the ui/RelativeTime module at this location in the DOM. Note the content is already present and in an acceptable format and the module only enhances that.

If you want a module to initialize only when it’s visible to a user, you can do so with conditions:

<!-- Show RelativeTime only if it is visible to the user -->
<time datetime="2017-01-01" data-module="ui/RelativeTime" data-conditions="element:{visible}">2017</time>
<!-- Keep showing RelativeTime after it was visible to the user -->
<time datetime="2017-01-01" data-module="ui/RelativeTime" data-conditions="element:{was visible}">2017</time>

Conditioner.js has quite an extensive list of monitors, which you use to define conditions. Don’t fret! You only have to include those you need, preventing the inclusion of unnecessary code.

You can also pass along options as a JSON string or a slightly more readable JSON variant.

<!-- JSON variant -->
<div data-module="ui/RelativeTime" data-options='unit:"seconds"'>...</div>
<!-- Or good old JSON -->
<div data-module="ui/RelativeTime" data-options='{"unit":"seconds"}'>...</div>

Top JavaScript Frameworks in 2017

The popularity of JavaScript in so many vibrant ecosystems of technologies, frameworks, and libraries is undoubtable. But, JavaScript comes in many features and many web developers are wondering where should you invest your time to get the most benefit? Which tech stacks are companies hiring for right now? Which ones have the most growth potential? Below are some JavaScript Frameworks in 2017 that is predicted will be popular. Check this out!

React

React is one of Facebook’s products; it is a JavaScript library for building user interfaces. It’s based on the idea of uni-directional data flow, meaning that for each update cycle:

  1. React takes inputs to components as props and conditionally renders DOM updates if data has changed for specific parts of the DOM. Data updates during this phase can’t retrigger the render until the next drawing phase.
  2. Event handling phase – after the DOM has rendered, React listens for and events, delegating events to a single event listener at the root of its DOM tree. You can listen to those events and update data in response.
  3. Using any changes to the data, the process repeats at 1.

Redux

Redux offers transactional, deterministic state management for your apps. In Redux, we iterate over a stream of action objects to reduce to the current application state. Redux is mandatory learning, even if you never use Redux for a production project. From Redux, you can learn the value of using pure functions and new ways to think about reducers. Reducers are general-purpose functions for iterating over collections of data and extracting some value from them. It is so useful that you can find Array.prototype.reduce in JS specification.

Angular

Angular 2 is the first feature to the wildly popular Angular framework from Google. Because of its popularity, people will look cool for those who can do it, but it is better to learning React first.

There are two reasons why some people have a preference for React over Angular 2:

  1. It’s simpler,
  2. It’s extremely popular and used in lots of jobs

Whatever your choice is, whether it is React or Angular 2, we recommend you to learn it for at least 6 months-1 year before you can jump to the other program.

RxJS*

RxJS is populary known as a collection of reactive programming utilities for JavaScript. It is quite similar with Lodash for streams. Reactive programming has officially arrived on the JavaScript scene. The ECMAScript Observables proposal is a stage-1 draft, and RxJS 5+ is the canonical standard implementation.

However in RxJS, you will find that you can’t just import the whole thing all at once. So, you can use the patch imports to reduce the size of your rxjs dependencies. Instead of, combating bundle boat while importing things.
