I want to set if Function Exists before Calling javascript can you help me how do this and apply on this script

I’m assuming that you’re wanting to check and make sure that lettering exists, try this:

Here’s an example:

if ( $.isFunction($.fn.lettering) ) {
    $(".cs-text-cut").lettering('words');
}
