JavaScript Loops

JavaScript Loops

Loops are used to execute a block of code multiple times.

for Loop

The for loop repeats a block of code a specific number of times.

for (let i = 0; i < 5; i++) {
    console.log("Iteration:", i);
}

while Loop

The while loop repeats a block of code as long as a condition is true.

let count = 0;
while (count < 5) {
    console.log("Count:", count);
    count++;
}

do...while Loop

The do...while loop executes the block of code at least once, then repeats as long as the condition is true.

let count = 0;
do {
    console.log("Count:", count);
    count++;
} while (count < 5);

for...of Loop

The for...of loop is used to iterate over iterable objects like arrays:

let fruits = ["Apple", "Banana", "Cherry"];
for (let fruit of fruits) {
    console.log(fruit);
}
