Control flow with if / else if / else blocks.

Match discrete values with switch and break/return.

Repeat work with for, while, do-while, and for…of / for…in.

Iterate with classic indexed for loops.

Loop while a condition remains true.

Run the body at least once with do…while.

Exit loops early with break; skip iterations with continue.

Add, subtract, multiply, divide, and use remainder/exponentiation.
