The apply function is Javascript does basically the same thing as the call function. BUT it has one distinct advantage to us as everyday programmers. Unlike the call function which takes in a variable(s) as the parameter(s) to execute a function against. The apply function takes an array. This may sound like a small difference, but when you think about the fact that a lot of data is stored in arrays already this function has a huge advantage to us as everyday programmers. I thought that was the end of what I wanted to know about the function, but then I did some reading online and come to find out there is another HUGE advantage to the apply function that I did not realize at first. Credit to www.w3schools.com for explaining how you can extend the Math objects functionality and run them on arrays using apply. A quick example of this would be if we had a an array of scores

	let scores = [100, 22000, 5000, 300 ];

And we wanted to get the high score from this array we can do it in one line such as

	let highScore = Math.apply.max(null, scores);

So the full script would be

let scores = [100, 22000, 5000, 300 ];
let highScore = Math.max.apply(null, scores);
console.log(highScore);

As the blog post above has pointed out arrays do not have a max function so using apply to barrow the functionality found in Math.max is a powerful way to extend the functionality of other already existing data stored in arrays, let your imagination run wild.
