Arrays come with a useful forEach
function that allows you to loop through the array.
var colors = ['red', 'blue', 'green'];
colors.forEach(function(color) {
console.log(color);
});
// red
// blue
// green
You can also get the index
in each loop as follows:
const colors = ['red', 'blue', 'green'];
colors.forEach((item, index)=>{
console.log(index, item)
});
// 0 'red'
// 1 'blue'
// 2 'green'
