In JavaScript, we use control structures primarily to control the flow of the program; how the commands execute. Control structures determine the direction in which a program flows, allowing for decision making, looping, and branching. This includes structures like:
- Conditional statements (
if,else if,else,switch) to execute code only when certain conditions are met. - Loops (
for,while,do...while) to repeat a block of code multiple times based on a condition. - Control flow commands (
break,continue) to alter the flow of loops.
So the correct answer to your question is the first option: Control the flow of the program; how the commands execute.
