How can I check the existence of an element in jQuery

Question

The current code that I have is this:

if ($(selector).length > 0) {
    // Do something here
}

Is there a more elegant way to approach this? Perhaps a plugin or a function?

Hello @ Arpit

In JavaScript, everything is 'truthy' or 'falsy', and for numbers 0 means false, everything else true. So you could write:

if ($(selector).length)

You don't need that >0 part.

Hope it helps!!
Thank you!!
