Be sure to know the difference between jQuery and Javascript. Javascript is what the browser understands. jQuery is written in Javascript, and is "just" a library to make a lot of commonly used design patterns in web design easier. Try to understand the basics of Javascript before dabbling in jQuery, otherwise you might run into more problems like these. — Jeff Huijsmans, Apr 13 '17 at 16:05

It is a shorthand for if else:

Translation:

if(13 == t.keyCode) { return (t.preventDefault(), !1); } else { return void 0; }

Its ternary operator. Shorthand for writting if/else
