Equality by checking each member
let list = []; for (let j = 0; j < 3; j++) { for (let i = 0; i < 100; i++) { list.push(i); } } const target = 67; for (let i = 0; i < list.length; i++) { if (list[i] == target) return true; } return false;
Equality by constructing set
let list = []; for (let j = 0; j < 3; j++) { for (let i = 0; i < 100; i++) { list.push(i); } } const target = 67; new Set(list).has(target)
