data.map(p => console.log(p))

what does this code do?

This is a function provided by Javascript to perform certain functions on every element of the array. The map method takes in a call-back function which returns a new array containing the result. for example.

Var array1 = [1,2,3,4,5];

var array2 = array1.map(element=> element * 2);

array2= [2,4,6,8,10].
