An infinite loop in programming is a loop that never terminates, meaning it continues to execute indefinitely. This can occur for a variety of reasons, such as an incorrect or missing loop termination condition, or a logical error in the loop body that prevents the condition from being met.
Infinite loops are generally considered bad because they can cause a program to crash or become unresponsive, consuming valuable system resources and potentially causing data loss or corruption. They can also cause performance issues, as the program may be stuck in the loop and unable to complete other tasks or respond to user input.
In some cases, infinite loops may be intentional, such as in server-side applications that need to continually listen for incoming connections. However, in most cases, it is important to ensure that loops have a well-defined termination condition to avoid infinite loops and their associated problems.

<script>
function first() {
document.write("This is from First Function <br>");

function second() {
document.write("This is from Second Function <br>");

This is infinite loop example. The functions first() and second() call each other recursively, meaning they call themselves over and over again without any stopping condition. As a result, the caller() function that invokes both first() and second() also goes into an infinite loop.
Infinite loops are generally bad because they can cause a program to become unresponsive, crash or consume a lot of resources such as memory or CPU time. This can lead to poor performance or even render the program unusable. It's important to make sure that loops and recursion have a stopping condition to prevent infinite looping.
In general, infinite loops do not cause direct damage to hardware. They are a software issue that can cause a program to become unresponsive and consume excessive CPU resources, which can slow down other processes running on the same system.
However, if a program is using hardware resources in a way that is not intended, it could potentially cause damage.
For example, if a program repeatedly writes data to a hard disk without proper error checking, it could cause the disk to fail. It's important to note that infinite loops are not necessarily malicious or harmful on their own, but they can cause issues when not properly handled.
