What is the forEach method in JavaScript?

What is the forEach method in JavaScript?

The forEach method is used to execute a provided function once for each array element.

Can you give me an example of how to use forEach?

Sure! Here's a simple example:

const numbers = [1, 2, 3, 4];
numbers.forEach(num => {
  console.log(num);
});

This will log each number in the array.

What if I want to modify the elements while using forEach?

The forEach method does not create a new array, but you can modify the original array inside the callback function.

Is forEach better than a regular for loop?

It depends on the use case. forEach is more concise and easier to read, but a regular for loop can be more flexible.
