• What is Filter()?

  • filter() is a method of the Array object.
  • It creates a new array with all elements that pass a test implemented by the provided function.
  • An element makes it to the new array if the function returns true for that element.

const nums = [1, 2, 3, 4];

const moreThanTwo = nums.filter((current, index, originalArray) => {
	return current > 2;
});

console.log(moreThanTwo) // [3, 4]
