What happens when you try to add two arrays together in JavaScript?

What happens when you add two arrays together in JavaScript? This weird functionality is important to watch out for, as it is unintuitive and could cause bugs in your code.

const bills = [125, 555, 44]
const tips = [54, 96, 32]
for(let i = 0;i < bills.length;i++)
total.push(bills[i] + tips[i])
you can simply loop through the array index to add them

Could we next time add a solution to solve it? :)

How the heck do we add two arrays, numerically, element by element. I tried many suggested options with total failures. Do you have yet another suggestion? I will try that too.

What will Happen, if you create a New array for a+b, and if you Set a Semikolon at the first Position of b. Then the result must be the merged array, right?

What is the proper way to add the arrays together?

A surprise to be sure, but not a welcome one.
