Operators are the four families that make JavaScript do things: arithmetic, assignment, comparison, and logical, plus the ternary shortcut and the truthiness rules behind real-world defaults. This cheatsheet gathers them all on one page, each snippet annotated line by line. Keep it open while you code, or save the image and pin it nearby.
