What is code, really?

Code is a recipe for a computer. A list of instructions written precisely enough that a machine - which has no common sense - can follow them step by step and get the same answer every time.

Everything you use - websites, games, banking apps, traffic lights, microwaves - is code running on hardware. Learning to read and write code is learning a new literacy.
