O(n²) Example

o(n²).js

const numbers = [1, 2, 3, 4, 5]
function logFiveTimes(numbers) {
	for (let i = 0; i < numbers.length; i++) { //O(n) --> linear time (run time increases at the same pace as the input)
		for (let i = 0; i < numbers.length; i++) { //O(n) --> linear time (run time increases at the same pace as the input)
		console.log(numbers[i]); //O(1) --> constant time (basic operation)
		}
	}
}
