    When you use a JS framework, you get up-to-date JavaScript tools and features that you can use for different use cases. This means that every time you develop an app, you don’t have to write code for each feature of the app from scratch. 

    JS frameworks save developers a lot of time and effort and let them build functional apps.

    While you can still build robust web apps without a JS framework, using a framework has become a staple of the modern programming approach.
