Framework vs Library
Libraries is a collection of code whereas framework is collection of libraries. Using frameworks provides a complete template. Using frameworks provides more organization and code efficiency than using libraries.
JS is one of the oldest languages and it has more frameworks than any other language. So, it has many frameworks but we will only be mentioning the popular ones here. To get, set, and go with your development project you should hire JS developers with the skills you need. Here are the most popular frameworks.
Node is a runtime environment which provides power of server-side scripting and using command line tools. With node you can run scripts on the server rather than client-side or front-end which increases the load speed.
Angular, just like Vue, builds SPAs. So, the content is dynamically loaded from server instead of browser so the application doesn’t need to be reloaded for new content.
Express is a true backend framework and works with Node.js APIs. It is a free and open source framework used to build web apps and you can even build APIs with it.
React is used for frontend development and creating interactive and modern UIs. However, React is not a framework, it is a library which is taken as a framework because it provides the functionalities a framework does. It provides features like hooks and hot reload.
How to Choose a framework
Selection between different frameworks should not be a difficulty if you know what you want. Similarly, if you want to hire JS developers then you should know what are your project requirements, the features you want and what type of work is to be done.
