Most used Javascript Frameworks

The Frameworks, also called frameworks, can be viewed as a toolbox that contains the components (tools) that a developer needs to build their application. This toolbox provides the general structure of the software and facilitates the developer's work in the development process. The main objectives pursued by a framework are: speed up the development process, reuse existing code and promote good development practices such as the use of patterns.

A web framework, therefore, are a set of tools, styles and libraries arranged through a base structure or skeleton, for the development of more scalable and easy-to-maintain web applications. Web development frameworks can be used for the development of web services, web API (Application Programming Interface) and other web resources.

JavaScript it is a powerful language, capable of providing effective solutions in most areas of technology. It is especially important because it is the only programming language that browsers understand, with which part of the frontend functionality in modern websites and web applications is developed.

angular.js

It is a Javascript frontend development framework that allows you to create SPA applications. It is free software promoted by Google, although now it is only under maintenance. It is a structural framework for dynamic web applications. It allows you to use HTML as a template language and allows you to extend the syntax of HTML to express your application components clearly and succinctly. Its data binding and dependency injection eliminates much of the code you currently have to write. And it all happens within the browser, making it an ideal partner with any server technology.‎

Angular.js changes static HTML to dynamic HTML. Its features like dynamic binding and dependency injection eliminate the need for code that we have to write in another way. AngularJS is growing fast and for this reason we have different versions of AngularJs, the latest stable being 1.7.7. It's also important to note that Angular is different from AngularJs. It is an open source project that anyone can freely use and modify. It extends HTML attributes with directives and data binds to HTML.

Key points:

AngularJS is a JavaScript framework primarily used for frontend development.
It is used to make single page applications (SPA).
It is open source and is completely free for everyone.
It uses the Model, View, Control (MVC) pattern to develop projects.

React.js

It is a Javascript library focused on the development of user interfaces. This is how the bookstore itself is defined and obviously, that is its main area of work. However, the truth is that in React we find an excellent ally to make all kinds of web applications, SPA (Single Page Application) or even mobile applications. To do this, around React there is a complete ecosystem of modules, tools and components capable of helping the developer to cover advanced objectives with relatively little effort.

React is based on a paradigm called component-oriented programming in which each component is a piece that the user can interact with. These pieces are created using a syntax called JSX allowing you to write HTML (and optionally CSS) inside JavaScript objects.

It is no coincidence that companies like Netflix, Airbnb, Dropbox, Paypal, Tesla, Whatsapp, Uber, etc. have opted for this technology, the investment made by Facebook together with the large number of developers who have contributed to this open source library make it a safe bet for the future.

vue.js

Created by Evan You, Vue.js is an open source, progressive JavaScript framework for building user interfaces (UIs) and single-page applications; is commonly known as Vue. This framework uses "high decoupling," which allows developers to progressively build user interfaces (UIs).

Modularizing libraries using a framework is common in frontend development. Both React and Angular have modularization. But what sets Vue.js apart from other alternatives is its “high decoupling”, how easy it is to extend the features, and how well all the parts work once more modules are included. For example, if we want to organize and render small visual components, all we need is the "core" Vue.js library; no need to include additional libraries.

Vue.js's component system is reactive, which means that Vue.js knows how to communicate via asynchronous events; for example, a child component can communicate with its parent component through events. Vue.js has a special command line (CLI) built in Node JS. This tool allows us to start a project using a standard model (or base template).

Ember.js

It's a framework JavaScript is open source and is based on the MVC (Model-View-Controller) architecture. According to its authors, the framework is designed “to create ambitious web applications”. Not only to create SPAs (Single-Page applications), but also to create desktop and mobile applications. It allows you to create client-side JavaScript applications by providing a complete solution that contains data management and application flow.

Some of these features that you will learn in the guides are:

Ember CLI - A set of robust development tools for creating, developing, and building Ember applications. Learn the basic commands from the CLI guides.
Components – The fundamental construct used in Ember apps, used to create reusable UI elements and define the layout and functionality of the app.
Routing - A core part of an Ember application. Allows developers to control the state of the application from the URL.
Services: the way to store long-term state in your application and transmit it.
Ember Data: Ember Data provides a consistent way to communicate with external APIs and manage application state.

Svelte.js

Svelte.js is a reactive and component-based framework that uses a build step when making changes to the DOM, in this article I will show you the benefits of using Svelte.

Svelte main features

Svelte joins the world of creating Web applications based on reactive components. With it we will be able to create interactive interfaces for our Web applications. One difference of this tool, with respect to others, is that it is not based on the virtual DOM, but rather it does a kind of compilation of the components when changes occur. Another very interesting functionality that Svelte has incorporated is its state manager. For this reason we will be able to create complex Web applications without having to resort to additional alternatives, such as Redux.

It is also to highlight its simple syntax and its compilation capacity, which offers us a result of less weight, compared to other alternatives available in the world of development.

If we take a look at the API we will find very interesting features for animations, transitions and events, among other options that also include possibilities to work with the life cycle. To complete, it is important to know that Svelte has been written by Rich Harris and was released in the year 2016. At the time of writing these lines, I can say that its update rate is very good. It is free and Open Source (with MIT License).

Polymer.js

Polymer is a library for the development of Javascript components and applications, which is based on the Web Components standard, so it focuses on all the features of native Javascript.

Polymer is a library that offers easy development of custom elements, or custom elements, also called simply components. Components are like new HTML tags, which can extend the functionality of the browser.

Its main feature is that Polymer is based on the Web Components Javascript standard, so it uses the possibilities offered directly by browsers and modern Javascript.

Polymer is a library created by Google. The team that makes Polymer is responsible for several products, including the Polymer library or "Polymer Library". Of all the products that the Polymer library offers, it is the first that they presented, which is currently undergoing maintenance.

Backbone.js

Backbone is a JavaScript framework based on the MVC architecture. In Backbone.js, the MVC view helps you implement controller-like component logic. The Backbone view can use engines like Mustache and Underscore.js. Backbone.js is an ideal choice for both front-end and back-end development because it supports REST APIs used to keep the front-end and back-end in sync.

To make full use of Backbone.js, JavaScript developers must choose from the following tools:

The BackboneJS ecosystem contains:

The Backbone library consists of events, models, collections, views, and a router.
Underscore.js, a JavaScript library with helper functions that you can use to write cross-browser JavaScript.
You can use template engines like Mustache and jQuery-tmpl.
BackPlug online repository with many ready-to-use solutions for Backbone applications.
Trunk builder command line interface for creating trunk applications.
Marionette, Thorax and Chaplin JavaScript libraries to develop the advanced architecture for Backbone applications.

Node.js

Node.js is a JavaScript environment that allows us to run on the server, asynchronously, with an event-oriented architecture and based on Google's V8 engine. It is a platform that is advancing very quickly and is becoming more and more present in the market.

You must remember that NodeJS is not a framework and it is not a programming language. Provides an event-driven, non-blocking (asynchronous) I/O and cross-platform runtime environment for building highly scalable server-side applications using JavaScript.

Features of Node.js

Asynchronous and Event Driven
very fast
Single Threaded but Highly Scalable
No Buffering
