How do spread and rest parameters work in JavaScript?

Can you explain the difference between spread and rest parameters in JavaScript?

Sure! Spread parameters allow you to expand an iterable (like an array) into individual elements, while rest parameters collect multiple elements into a single array.

Can you give me an example of how to use both in a function?

Absolutely! Here's an example:

function myFunction(...args) {
  console.log(args);
}

const arr = [1, 2, 3];
myFunction(...arr);

In this case, ...arr spreads the array elements into the function.

Are there any compatibility issues with older browsers?

Yes, spread and rest parameters are not supported in Internet Explorer. You might need to use Babel to transpile your code for compatibility.

What are some best practices when using these parameters?

It's best to use rest parameters when you don't know how many arguments will be passed, and use spread parameters when you want to pass an array as individual arguments.
