Array Mapping In Javascript

// function to return the square of a number function square(number) { return number * number; Const roots = numbers.map((num) => math.sqrt(num)); For example, suppose you have the following array element:

Multiply all the values in an array with 10: Const arr = [1, 2, 3]; This method doesn't change the original array.

For this instance, we will take an object that has an array value for each key.

Numbers is still [1, 4, 9] Return a new array with the square root of all element values: For this instance, we will take an object that has an array value for each key. Let arr = [3, 4, 5, 6];
