What are the best practices for using the arguments object in JavaScript?

The arguments object is an array-like object available within functions. Best practices include using rest parameters instead for better readability and performance.

Why should I prefer rest parameters over the arguments object?

Rest parameters provide a true array, making it easier to work with methods like map, filter, and reduce, and they improve code clarity.

Can you give an example of using rest parameters?

Sure! Instead of using function myFunc() { console.log(arguments); }, you can write function myFunc(...args) { console.log(args); }.

Are there any limitations to using the arguments object?

Yes, the arguments object does not have array methods, and it can lead to confusion in arrow functions since they don't have their own 'this' context.
