What are JavaScript frameworks?


JavaScript frameworks are application frameworks that allow developers to manipulate code to meet their particular needs.

Web application development is like building a house. You have the option of creating everything from scratch with construction materials. But it will take a long time and can incur high costs.

But if you use ready-made materials, such as bricks, and assemble them according to the architecture, construction is streamlined and saves money and time.

Application development works in a similar way. Instead of writing all the code from scratch, pre-written code can be used as building blocks based on the architecture of the application. Frameworks can be adapted to the website design more quickly and make it easier to work with JavaScript.


How to use JavaScript frameworks


To use a JavaScript framework, read the documentation for the JS framework you intend to use and follow the steps.

What are JavaScript frameworks for?

  • To build websites
  • Front-end application development
  • Back-end application development
  • Hybrid application development
  • E-commerce applications
  • Build modular scripts, e.g. Node.js
  • Manually update the DOM
  • Automate repetitive tasks using templates and bi-directional linking
  • Develop video games
  • Create image carousels
  • Code testing and debugging
  • To group modules

How JavaScript libraries and frameworks work


The difference between JavaScript libraries and frameworks lies in their flow of controls. They are simply opposite in flow, or reversed.

In JS libraries, the primary code calls the function provided by a library.

In JS frameworks, the framework itself calls the code and uses it in a specific way. It defines the overall design of the application.

In short, JavaScript libraries can be thought of as a particular function of the application. In contrast, the framework acts as its skeleton, while an API acts as the connector that binds them together.

Commonly, developers start the development process with a JS framework and then complete the application's functions with JS libraries and the help of an API.


JavaScript libraries and frameworks are effective in speeding up the development process of your website or application. And, as a web developer, using the right one for your project is crucial.

Different libraries and frameworks serve different purposes and have their own sets of pros and cons. Therefore, you should choose them based on your unique requirements and future goals associated with a website or application.

I hope this extensive list of JavaScript libraries and frameworks will help you choose the right one for your next project.
