Arrays

Array.filter()

Create a new array with only elements that pass a test you include as a callback function. The callback accepts three arguments: the current item in the loop’s value, its index, and the array itself. All three are optional.

let numbers = [1, 2, 7, 42, 99, 101];

// Create a new array with only numbers greater than 10
let biggerThanTen = numbers.filter(function (item) {
	return item > 10;
});

// logs [42, 99, 101]
console.log(biggerThanTen);
