jQuery selecter whats difference between jQuery(“element”) and $(“element”)?

Just a little curious..

Why sometime I see it written as $("#SomeElementId") and sometime as jQuery("#SomeElementId") ? What is the exact difference ?

Answer 1

$ is an alias of the jQuery namespace. It’s just quicker to type. It is avoided normally when there is the potential for conflict with other libraries that also utilise $.

jQuery always declares jQuery but will only declare $ unless jQuery.noConflict() is called.

Either way, a common pattern is to reference $ as a local variable in a closure, via an immediately-executed function:

(function($) {
    //all your code here, which can reference $
})(jQuery);
