Infinite While Loop

An infinite while loop is a loop that continues to execute indefinitely because the loop’s condition always evaluates to true.

This can happen either intentionally or unintentionally, and it can cause a program to become unresponsive or crash if not handled properly.

Example

let num = 1;
while (num < 10) {
    console.log("This loop will run forever!");
}

In this example, the condition num < 10 is always true, so the loop will never stop running. This is an example of an unintentional infinite loop.

To avoid creating an infinite loop by mistake, make sure your loop’s condition will eventually become false.

Making sure our variable updates at every loop towards the false condition:

let num = 1;
while (num < 10) {
    console.log("This loop will run forever!");
    num++;
}

Use Case: Game Loops

Game loops are a classic example of infinite loops used in programming. They are essential for running the main logic of a game, continuously updating the game state, processing user input, and rendering graphics.
