Lesson 4 of 10
Loops
Loops repeat code. A for loop runs a specific number of times. A while loop runs while a condition is true. A for...of loop iterates over arrays.
JS
// For loop
for (let i = 0; i < 5; i++) {
console.log(i); // 0, 1, 2, 3, 4
}
// While loop
let n = 0;
while (n < 3) {
console.log(n);
n++;
}
