Script Preparation code:

var arr = [];
var max = 1000;
var valueToFind = 500;
for (var i = 0; i < 1000; i++) {
	arr[i] = Math.floor(Math.random()*max);

Tests:

arr.find(item => item === valueToFind);
arr.find(item => item === valueToFind);

const len=arr.length;
for (var i = 0; i < len; i++) {
  if (arr[i]===valueToFind) {
    break;
  }
}

 
const len=arr.length;for (var i = 0; i < len; i++) {  if (arr[i]===valueToFind) {    break;  }}
