JavaScript is the most popular language on the web. If you have ever worked with JavaScript, then you know that it requires a lot of effort to develop and maintain a broad application. 

When beginner developers start learning JavaScript, they get attracted to JavaScript frameworks.

So, do you use any JavaScript framework or JavaScript Library for web development? most probably you do. JavaScript frameworks and JavaScript libraries have their own pros and cons.

 In this Article, I am going to highlight 7 best JavaScript Frameworks and libraries to learn in 2019 and takes a bird’s eye view of how each one of them can ease your JavaScript App development.

  Framework vs Library

Framework are backing for structures, HTTP solicitations, and a great deal more. It’s a finished toolbox to building a web application. 

Frameworks are bigger than libraries. They include everything you may need to build applications

  Quoting Martin Fowler:

A library is essentially a set of functions that you can call, these days usually organized into classes. Each call does some work and returns control to the client.

A framework embodies some abstract design, with more behavior built in. In order to use it you need to insert your behavior into various places in the framework either by subclassing or by plugging in your own classes. The framework’s code then calls your code at these points.

If you don’t need so many capabilities provided by the juggernauts like Angular or React, you can bet on a less complex solution, e.g., Webix.

[gitrepo author=”webix-hub” repo=”webix”]

It’s a very fast and lightweight JavaScript UI library and framework with 100 responsive UI widgets and CSS / HTML5 JavaScript controls. Webix allows creating various types of web applications (it also incorporates a micro-framework for building single-page apps) and suits for instant and cost-effective app prototyping.

  2. Vue

Vue is a progressive, incrementally-adoptable JavaScript framework for building UI on the web.

According to Github, Vue is most most Popular JavaScript Library on Earth with 118k+ stars.

Vue is a library for creating web interfaces. Vue is Simple, minimal core with an incrementally adoptable stack that can handle Apps of any scale.

 3. React

React is a library, not a framework. Lots of people name it a framework or compare it to frameworks. The reason React is often mistaken as a framework is because it appears like frameworks are React’s competitors.

According to Microsoft’s Github, React is second most Popular JavaScript Library on Earth with 114k+ stars

React does not come with any REST tools for making HTTP requests. React does not come with any tools to handle client-side routing. It is just a library that helps you build amazing user interfaces. 

  4. Angular

Angular is a Typescript (Superset of JavaScript) framework that you can use to build large scale single page web applications. Angular comes with most everything you need to get some web development done.

[gitrepo author=”angular” repo=”angular”]

The whole concept of application structure has changed in Angular 2+. Previously it was the MVC framework that allowed you to create applications in the pattern of rather tightly coupled entities like controllers, views, services, etc.

 The purpose of the Angular 2+ application architecture is to create components that don’t depend on each other, which are as loosely coupled as possible.

  5. React Native

The React Native is an outcome of the idea behind Facebook’s Hackathon Project, to bring some of the web development features like fast iteration, to mobile app development.

[gitrepo author=”facebook” repo=”React-native”]

In React Native, you will build a real app apart from the HTML5 app or a hybrid app, which is unique enough and difficult to distinguish from apps which are developed using Java or Objective-C.

The feature Hot Reloading allows you to run new code when you are retaining the application state.

  6. Ember

Ember.js is a JavaScript framework that greatly reduces the time, effort and resources needed to build any web application.

[gitrepo author=”emberjs” repo=”ember.js”]

Ember.js is focused on making you, the developer, as productive as possible by doing all the typical, repetitive, yet essential, tasks involved in most web development projects.

  7. Polymer

Polymer lets you build encapsulated, reusable elements that work just like standard HTML elements, to use in the construction of web applications.

[gitrepo author=”polymer” repo=”polymer”]

The polymer is a lightweight library built on top of the web standards-based Web Components APIs and makes it easier to create your very own custom HTML elements.

  8. Aurelia

The Aurelia framework brings together all the required core aurelia libraries into a ready-to-go application-building platform.

[gitrepo author=”aurelia” repo=”framework”]

Aurelia is a collection of Modern JavaScript modules, which when used together, function as a powerful platform for building a browser, desktop and mobile applications, all open source and built on open web standards.

JavaScript is evolving & modern databases such as MongoDB and CouchDB use JavaScript as their scripting and query language. JavaScript has become an important platform outside browsers as well. You can surely use any JavaScript library or framework of your preference, but the best choice will facilitate your work a lot.
