What are the differences between native modules and pure JavaScript?

What are the differences between native modules and pure JavaScript?

Native modules are built-in functionalities provided by the JavaScript environment, while pure JavaScript refers to code written without any external libraries or frameworks. Native modules often offer better performance and integration with the environment.

Can you give me examples of native modules?

Sure! Examples of native modules include 'fs' for file system operations, 'http' for creating web servers, and 'path' for handling file paths in Node.js.

What are the advantages of using native modules?

The advantages of using native modules include improved performance, better security, and access to system-level features that pure JavaScript cannot provide.

Are there any downsides to using native modules?

Yes, some downsides include potential compatibility issues across different environments and the need for a deeper understanding of the underlying system.

When should I use pure JavaScript instead of native modules?

You should use pure JavaScript when you want to ensure maximum compatibility across different environments or when you are building lightweight applications that don't require system-level access.
