Question

I decided to set alias for $, because dollar sign is hardly accessible on keyboard:

$(function(){
    var ff = $;
    ff('p').hide();
});

Now I use ff instead of $ everywhere. Is it considered good or bad practice?

Answer 1

The $ name is itself an alias, the jQuery function is really named jQuery, so you can use that instead:

jQuery('p').hide();

The ready event handler also has a parameter that you can use instead of copying the global jQuery reference:

jQuery(function(ff){

  // now ff is an alias for the jQuery function:

  ff('p').hide();

});
