In the world of programming, infinite loops can be both a blessing and a curse. While they are essential for certain tasks, they can also lead to disastrous consequences if not handled properly.

In JavaScript, infinite loops are particularly prevalent, and understanding how to write, control, and terminate them is crucial for any developer.

What is an Infinite Loop?

An infinite loop is a sequence of instructions that repeats indefinitely until an external force intervenes. In other words, it’s a loop that never stops executing unless you manually terminate it or the program crashes. Here’s a simple example of an infinite loop in JavaScript:
