Script Preparation code:

var array = [];
for (let i = 0 ; i < 10000 ; i++) {
	array.push ({ value: Math.floor (Math.random () * 1000) });
}

Tests:

reversed for loop
const value = Math.floor (Math.random () * 1000); let found = undefined; for (let i = array.length - 1 ; i >= 0 ; i--) { const cell = array[i]; if (cell.value === value) { found = cell; break; } }
find method =>
const value = Math.floor (Math.random () * 1000); let found = array.find ((cell) => cell.value === value);
find method function
const value = Math.floor (Math.random () * 1000); let found = array.find (function (cell) { return cell.value === value });
