JavaScript Loops

The javascript loops are used to execute a block of code repeatedly until a certain condition is met. There are three types of loops in JavaScript: for, while, and do-while.

1. for loop: The for loop is used when we know how many times we want to execute the loop. It consists of three parts: the initialization, the condition, and the increment/decrement.

for (let i = 0; i < 10; i++) {
    console.log(i);
}

2. while loop: The while loop is used when we don’t know how many times we want to execute the loop. It executes the code block as long as the condition is true.

let i = 0;
while (i < 10) {
   console.log(i);
   i++;
}

3. do-while loop: The do-while loop is similar to the while loop, but it always executes the code block at least once before checking the condition.

let i = 0;
do {
   console.log(i);
   i++;
} while (i < 10);
