  • Smallest example: the smallest Math.pow example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Math.pow().
  • From the example next to this theory: Raises a number to a given power.
  • Trap: only saying “Math.pow” with no example. Fix that before you talk about advanced JS.

Math.pow() — working example

// Topic: Math.pow()
const nums = [1, 2, 3];
const doubled = nums.map((n) => n * 2);
console.log(doubled);
console.log(doubled.reduce((a, b) => a + b, 0));

Math.pow(): map then reduce on [1, 2, 3]. Say both prints.
