jQuery advantages/differences in .trigger() vs .click()

In terms of performance, what are the gains (or just differences) between:

$('.myEl').click();

and

$('.myEl').trigger('click');

Are there any at all?

This is the code for the click method:

jQuery.fn.click = function (data, fn) {
    if (fn == null) {
        fn = data;
        data = null;
    }

    return arguments.length > 0 ? this.on("click", null, data, fn) : this.trigger("click");
}

as you can see; if no arguments are passed to the function it will trigger the click event.

Using .trigger("click") will call one less function.

And as @Sandeep pointed out in his answer .trigger("click") is faster:

As of 1.9.0 the check for data and fn has been moved to the .on function:

$.fn.click = function (data, fn) {
    return arguments.length > 0 ? this.on("click", null, data, fn) : this.trigger("click");
}

i think that

$('.myEl').trigger('click');

is better because it saves you a function call as $('.myEl').click(); just calls that funciton. Look at the code from jQuery source

jQuery.each( ("blur focus focusin focusout load resize scroll unload click dblclick " +
	"mousedown mouseup mousemove mouseover mouseout mouseenter mouseleave " +
	"change select submit keydown keypress keyup error contextmenu").split(" "), function( i, name ) {

	// Handle event binding
	jQuery.fn[ name ] = function( data, fn ) {
		if ( fn == null ) {
			fn = data;
			data = null;
		}

		return arguments.length > 0 ?
			this.on( name, null, data, fn ) :
                    //here they call trigger('click'); if you provide no arguments
			this.trigger( name );
	};

	if ( jQuery.attrFn ) {
		jQuery.attrFn[ name ] = true;
	}

	if ( rkeyEvent.test( name ) ) {
		jQuery.event.fixHooks[ name ] = jQuery.event.keyHooks;
	}

	if ( rmouseEvent.test( name ) ) {
		jQuery.event.fixHooks[ name ] = jQuery.event.mouseHooks;
	}
});

for performance kind .check here.. http://jsperf.com/trigger-vs-not-trigger Both are almost same...click() is shorthand of trigger('click').

Check http://api.jquery.com/click/ :

> In the third variation, when .click() is called without arguments, it > is a shortcut for .trigger("click").

It seems they are the same.
