Easier loops with forEach

Ever wanted to have an easier way to loop over a JavaScript List aka Array? You are in luck you can use the forEach method.

You can loop over this dataset:

const fruits = [
    {name : "oranges", day : Monday, qty : 8},
    {name : "apples", day : Tuesday, qty : 5},
    {name : "pears", day : Wednesday, qty : 1},
    {name : "oranges", day : Thursday, qty : 3},
    {name : "apples", day : Friday, qty : 4},
    {name : "oranges", day : Friday, qty : 13}
]

Using forEach like this:

fruits.forEach(function(fruit){
    // print fruit details
    console.log(fruit.name + " " + fruit.day);
});

The forEach method is an easy way to loop over a list, not needing any counter. The function passed into forEach will be called with each entry in the fruits list. How nice is that!
