- Gleam doesn't have loops, instead iteration is done through recursion, that is - through top-level functions calling themselves with different arguments. -

-

- A recursive function needs to have at least one base case and at - least one recursive case. A base case returns a value without calling - the function again. A recursive case calls the function again with different - inputs, looping again. -

-

- The Gleam standard library has functions for various common looping patterns, - some of which will be introduced in later lessons, however for more complex - loops manual recursion is often the clearest way to write it. -

-

- Recursion can seem daunting or unclear at first if you are more familiar with - languages that have special looping features, but stick with it! With time - it'll become just as familiar and comfortable as any other way of iterating. -
