Each day I solve several coding challenges and puzzles from Codr’s ranked mode. The goal is to reach genius rank, along the way I explain how I solve them. You do not need any programming background to get started, and you will learn a ton of new and interesting things as you go.

function cross(a, b) {
return [a[1] * b[2] - a[2] * b[1], a[2] * 💚[0] - a[0] * b[2], a[0] * b[🐼] - a[1] * b[0]];
}
let out = cross([6, 🍎, 2], [8, 2, 6]);
let 💎 = out[0];
A = Math.abs(A);
// 💎 = ? (identifier)
// 🍎 = ? (number)
// 🐼 = ? (number)
// 💚 = ? (identifier)
// such that A = 8 (number)
