Its dual integration way is one of the most attractive features used for making high-end SPA or Single Page Applications. It is an abundant dependable platform for developing cross-platform.

4. Ember.js

The intro of Ember.js to the software market was in 2015, and since then, it has increased admiration by its wide application area. The features of Ember.js provision two-way data binding and hence, begin a dependable platform for handling difficult User Interfaces. Popular websites like Netflix, Linked In, Nordstrom, and many more use the Ember.JS platform for their websites.

5. Meteor

Meteor’s application area (aka Meteor.js or MeteorJS) work for the name itself since it is diverse as it covers virtually the important portion of the software development. Usages of this framework comprise significant zones like back-end development, management of the database, business logic, and version of the front-end.

6. Mithril

Mithril may be a client-side JavaScript framework that’s used primarily in developing Single Page Applications. As there stay no by-product functions from a base category, the framework’s implementation is additionally easy. It’s tiny (< 8kb gzip), quick and provides routing and XHR utilities out of the box. It’s a number of options almost like react.

7. Node.js

Node.js could be a server-side JavaScript run-time atmosphere, which works on cross platforms and is an ASCII text file. The framework is capable of driving asynchronous I/O with its event-driven design. It works within the JavaScript Runtime atmosphere and shows JAVA’s similar properties like threading, packaging, o forming loops.

8. Polymer

The chemical compound is associated with the ASCII text file JavaScript library developed by Google, which might produce the website’s components while not reaching a fancy level.
