Execute jQuery code in WordPress

Most of the time jQuery codes are not working properly on WordPress theme. Add two line of code at the beginning and ending in js file.

Suppose custom_excellent_programming_tricks.js is the js file and code inside would be          
(1) (function($) { 
    //alert();
})( jQuery );
(2)
jQuery(document).ready(function( $ ) { 
    // //alert();
});
(3)
(function($) {    $(document).ready(function() {       
               // alert('adaaa');       
               // Code...    });
      })( jQuery );
(4)
$(function(){
             $(document).ready(function() {
                  //alert();
                 // Code...
             });
})(jQuery);
or
(5) (function() { ...})();
or
(6) jQuery(document).ready(function( $ ) { ... });

1. Mainly $(function(){ ........  })(jQuery); or (function() { ...})();
2. functions.php
1. require get_template_directory().'/inc/enqueue.php';

* If  HTML 'onclick' not working, using jQuery [ Like $( '#ept' ).on( 'click', function( event ){ ... }); ] code is better than tuning WordPress.
