10 Best Javascript Frameworks To Rely Upon

To start with , Name One Technology that is used for both Frontend and backend development.

Well, without an iota of doubt, the answer is JavaScript. The high-level interpreted language is a multipurpose language supported by web browsers and is used for testing websites and web applications too.

It is accepted as a core technology that supports object-oriented programming styles. It allows easy integration with APIs or Application Programming Interface for smooth operations on arrays and regular expressions.

Javascript with its versatility offers many frameworks and libraries each having its own I/o functions like graphics, networking, and usage. The library allows the apps to detect the runtime environment. On the other hand JavaScript libraries with full-stack properties are classified as Framework. It’s a hard decision to choose the best framework for backend and frontend amongst the list of JavaScript networks. Here is a small list of frameworks that are versatile and embrace all the characteristics of a good framework/library.

Frontend frameworks

JavaScript is a frontend framework is preferred by many web developers as it is backed up with numerous features. Here are the 3 best frontend technologies that pave the path for development in 2021:

React js

React js was initially introduced by team Facebook in the year 2011. It is a component-based, functional open-source network that creates interactive user interfaces for single-page applications. React makes the use of Virtual DOM wherein it renders only those components that have changed instead of rendering the whole page. React js Web developers make use of simple JSX syntax and a declarative programming style.

Backend Javascript frameworks

Javascript has made its unique positioning as one of the most preferred programming languages. It offers versatility and performance with its back-end server-side development with Node JS. Here are a few Server-side javascript frameworks each having its own plate offering scalability and flexibility.

Express js

Express js was originally introduced in 2010 as an open-source minimal web framework for Nodejs. It is positioned as the best javascript framework for backend with node js for application in MERN/MEAN stacks. Express js as the name suggests offers rapid server-side coding that makes complex tasks to be resolved in just a few minutes using Node js. Further, it promises efficiency as it helps to template engine to dynamically render HTML pages on the server-side rather than Client side.

Websites built with Nuxt. js: Note.com, Up work, Fox News, Gitlab.

Wrapping it up!

Ever since JavaScript has launched its frameworks they have been widely accepted by web developers. They offer development in both frontend and backend wherein each framework has its own pros and cons. It’s up to the choice of the developer to choose the one that is best suited to the project requirements. While performance and efficiency are the prime parameters that influence this decision, learning curve, complexity, and community support are other important factors that are considered while selecting the framework. Web developers have their own personal favorites while JavaScript as a complete universe embraces all of them together in the web world.
