Loops
Loops offer a quick and easy way to do something repeatedly.
You can think of a loop as a computerized version of the game where you tell someone to take X steps in one direction then Y steps in another; for example, the idea “Go five steps to the east” could be expressed this way as a loop:
for (var step = 0; step < 5; step = step + 1) {
// Runs 5 times, with values of step 0 through 4
console.log('Walking east step number:' + step);
}
There are many different kinds of loops, but they all essentially do the same thing: they repeat an action some number of times (and it’s actually possible that number could be zero).
The statements for loops provided in JavaScript are:
- for statement
- do…while statement
- while statement
- for…in statement
- for…of statement
