JavaScript Control Flow and Loops Cheatsheet

Control flow is how a script starts making decisions: if/else and switch choose a path, the loop family repeats work, and break and continue steer from inside. This cheatsheet gathers every construct on one page, each snippet annotated line by line. Keep it open while you code, or save the image and pin it nearby.

For the full background, read the guide to JavaScript control flow and loops. To practise, work through the code-along workbook.
