What is Js Map From Array?

Js Map From Array is a built-in JavaScript method that allows you to create a new array by manipulating the elements of an existing array. It takes a callback function as an argument, which is called on each element of the array and returns a new value. The new values returned by the callback function are then used to create a new array.

How Does Js Map From Array Work?

When you call the Js Map From Array method on an array, it creates a new array with the same length as the original array. It then calls the callback function on each element of the original array, passing in the current element, index, and the original array as arguments. The new value returned by the callback function is then added to the new array. Once the callback function has been called on each element of the original array, the new array is returned.
