 * I try doing theme customization.
    I created “Setting” and assigned it to “Control”,
   and created custom.js with wp.customize(…); BUT(!) browser console raise error:
   TypeError: wp.customize is not a function.
 * In browser console, I type: typeof wp.customize and result: “function”
 * Summary: live-preview not working.
 * What the problem?

                   $( '.awesome-slogan h3' ).html( to );
               } );
           } );
   
       } )( jQuery );

 * Problem solved.
    I used other jQuery version on front-end. In customization mode,
   jQuery embedded conflict with my jQuery. I fixed it.
 * bdanzer29, thx.
