When is it a good idea to build a new function for an operation?

As in, "for how small of an operation is it worth building a function?" Does it depend on how many times you're going to use it?

Often yes, it's advised that you write a function as soon as you need something more than once. Modern compilers can generally inline' code -- meaning that they can detect when a function is relatively short and replace the function call with the code in the function itself, thus removing any performance impact from having too many' function calls. This is, as usual, something you get a feel for, but small functions are not something to be afraid of. If what it does is not particularly evident, you can move a piece of code into a function so that you can give the function a descriptive name and then when it's used the code is clearer.
