trigger('click') vs trigger('click')[0]

Question

I am unable to differentiate between trigger('click') vs trigger('click')[0], is there any difference between them?

Where did you see any use of `trigger('click')[0]`??? – A. Wolff Dec 06 '17 at 13:17 — A. Wolff, Dec 06 '17 at 13:17

trigger('click') calls the trigger method with the 'click' parameter.

trigger('click')[0] calls the trigger method with the 'click' parameter, and accesses the first element of whatever it's returning.

A lot of methods in jQuery return the original jQuery collection to allow for easier chaining.

For instance

jQuery("body").trigger("click").css("background", "red"); 
// returns the jQuery collection.

If you use an index to access a jQuery collection, you'll get the corresponding DOM element, in my example, document.body.
