Can you give me some examples of while loops in JavaScript?

Can you give me some examples of while loops in JavaScript?

Sure! A while loop in JavaScript repeatedly executes a block of code as long as a specified condition is true. Here's a simple example:

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

This will print numbers 0 to 4.

What happens if the condition is never false?

If the condition never becomes false, the while loop will create an infinite loop, which can crash your program. For example:

let i = 0;
while (i < 5) {
    console.log(i);
    // i is never incremented
}

This will run indefinitely.

Can you show me a while loop that sums numbers?

Absolutely! Here's an example that sums numbers from 1 to 5:

let sum = 0;
let number = 1;
while (number <= 5) {
    sum += number;
    number++;
}
console.log(sum); // Outputs: 15

How can I avoid infinite loops?

To avoid infinite loops, ensure that the loop's condition will eventually become false. Always update the variables involved in the condition within the loop body.
