Rest Parameters

The add() function in rest_parameters.js adds two numbers together.

This is fine... but what if we wanted to add any amount of numbers together? 🤔

If you run the test file using:

            npm test rest_parameters.test.js

You'll notice the second test fails:

expect(add(1, 2, 3, 4, 5)).toBe(15);

The function only takes two parameters, so in this test numbers 3, 4 and 5 are getting ignored!

Using Rest Parameters and some kind of forLoop (your choice!), refactor this function so that it can add together any number of arguments and fix the failing test.

👉 Hint: make sure you're in the correct folder before running these commands. You will also need to console.log() your function to see any output.

👉 Hint: If you get stuck, use the MDN documentation to help you: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/rest_parameters

Good luck! 🙌
