Define an exists() function in Jquery

When we are in web development we have to check element is exist using Javascript. Below way we can check it.

console.log($('#elem').length == 1 ? "exists!" : "doesn't exist!");

But it can be cumbersome

So we can define a Jquery function as below

jQuery.fn.exists = function(){ return this.length > 0; }

console.log($('#elem').exists() ? "exists!" : "doesn't exist!");

Is it nice?…
