What are the differences between JavaScript frameworks and libraries?

JavaScript frameworks are collections of pre-written code that provide a structure for building applications, while libraries are sets of functions and tools that you can call upon to perform specific tasks. Frameworks dictate the architecture of your application, whereas libraries offer flexibility and can be used as needed.

Can you give me examples of popular frameworks and libraries?

Sure! Popular JavaScript frameworks include Angular, React, and Vue.js. Examples of libraries are jQuery, Lodash, and D3.js.

When should I use a framework instead of a library?

You should consider using a framework when you need a structured approach to building a large application, as it provides guidelines and best practices. Libraries are better for smaller projects or when you need specific functionalities without the overhead of a full framework.

Are there any performance differences between them?

Yes, performance can vary. Frameworks may introduce more overhead due to their structure and features, while libraries can be more lightweight and faster for specific tasks. However, the performance also depends on how you implement them.
