for loop 3 javascript code example

Example 1: javascript loop through array

var colors = ["red","blue","green"];
colors.forEach(function(color) {
  console.log(color);
});

Example 2: use these instead of a for loop javascript

const array = [1,2,3,4,5];const evenNumbers = array.filter(function(elem) {   // expressions that return 'true' are retained   return elem % 2 == 0;});
