JavaScript Looping Statements
Loops allow you to run a block of code multiple times.
JavaScript provides these main loops:
1.) while Loop
Used when you don’t know the exact number of repetitions, but repeat until a condition becomes false.
Syntax
while (condition) {
// code
}
Example
let i = 1;
while (i <= 5){
document.write(i);
i++;
}
2. for Loop
Used when you know how many times you want to run the loop.
Syntax
for (initialization; condition; increment) {
// code
}
Example – print 1 to 5
for (let i = 1; i <= 5; i++) {
document.write(i);
}
