Function-level programming

Function-level programming is a way of writing computer programs by using small, self-contained pieces called functions. Think of it like building with Lego blocks - each block is like a function, and you can put them together in different ways to create bigger things.

Functions are like little machines that take inputs (like numbers or words) and turn them into outputs (like answers or messages). They only do one thing, but they do it really well. For example, you might have a function that adds two numbers together, and another function that checks if a word is a palindrome.

By focusing on writing small, specialized functions, you can create programs that are easier to understand and modify. It's like having a toolbox with lots of different tools - you can choose the right one for the job, and you don't have to worry about each tool doing more than it needs to.

Overall, function-level programming is a way of programming that emphasizes creating small, reusable functions that work together to create more complex programs.
