JavaScript Control Flow

Control flow is how programs decide what to do next. If a user is logged in, show the dashboard; otherwise, redirect to login. If a cart total exceeds a threshold, apply a discount. These everyday behaviors all depend on conditionals and loops.

This module walks through if/else, switch, for and while loops, and how to combine them without losing readability. Visual step-throughs help you see exactly which branch runs and how loop counters change on each iteration.
