Javascript Array map methods

 The map() method is used to get a modified version of the array or a reduced value using callback functions. map() applies a function to each array element and creates a new array of the returned values

Example :1 

const listArray = [1,2,3,4,5]

const listArray = listArray.map(Item => {

    return item * 2;

})

console.log(listArray);

Output : [2,4,6,8,10]
