The Multiplier Map

Mission Briefing

The Grand Alchemist has a collection of raw ores that all need exactly the same treatment. You must build a factory line that processes every single item!

The Concept: Array Transformation

The .map() method is a Higher-Order Function. It creates a new array by calling a provided function on every single element in the original array. Example:

const doubled = [1, 2].map(x => x * 2); // Returns [2, 4]

The Objective

Your function receives an array nums.

1. Use the .map() method to iterate over nums.
2. Return a new array where every number has been multiplied by 2.
