Top 5 JavaScript Frameworks to Learn in 2019

Obviously, there are a plethora of JavaScript frameworks. While most of them either offer front-end or back-end development, some others are isomorphic i.e. they enable development on both sides. Among all the various JS frameworks, none can be labeled as the best. This is because each one of them has their own advantages and issues over others.

Hence, while a specific JavaScript framework can be superior to others in some contexts, it might be considered undesirable in other cases. Therefore it’s important to know the downsides and upsides of a JS framework to gain the best out of it.

JavaScript has already made it to the list of the best programming languages to learn in 2019. Therefore, it is about time to discuss some of the best JS frameworks that will be dominating 2019. As such, here is our pick of the top 5 JavaScript frameworks to learn in 2019:

Meteor.js

Type – Isomorphic
Launched In – 2012

Incepted for facilitating rapid development of mobile and web applications completely in JS, Meteor.js is an isomorphic JavaScript. Also known as Universal JavaScript, such a framework allows the creation of apps that can run both on the client as well as the server.

MeteorJS comes readily equipped with essential features pertaining to backend development, business logic and database management, and frontend rendering. The most desirable quality of the JavaScript framework is that you require only JavaScript knowledge for an end to end application development, nothing more.
Ever since its launch back in 2012, Meteor.js has garnered a huge and active community. As MeteorJS is modular, selective packages and libraries can be used on demand. Moreover, the Universal JavaScript boasts an active development. All these qualities make it one of the most important JS frameworks to start learning in 2019.
