ScriptdrillSplit into chunks
A JavaScript exercise from Scriptdrill. Solve it with a code editor in your browser that runs your function against example and hidden tests, and it is checked the moment you submit.
The task
Split `arr` into arrays of `size` items each. The last chunk holds whatever is left, so it can be shorter. `size` is at least 1. Do not change `arr`.
What this exercise teaches
A loop with i += size visits the start of each chunk, and slice copies that piece, clipping at the end of the array. The number of chunks is the length divided by size, rounded up.
A hint if you get stuck
Step through the array `size` at a time and take `arr.slice(i, i + size)`. `slice` never changes the original.
