MDN is not a guide or tutorial. It is more like a manual or reference, searching a manual or reference, works only when you know what you are looking for. Reading it like a book is better way to use it until you are familiar with it. Yes it takes more time but it pays off.
Learning of the manual once you get used to it is better because, You get answers to questions that you did not know you had . It gives you a comprehensive understanding of the entire feature set, not just the stuff that looks important now .
Copy pasting a implementation of stackOverflow/ w3schools etc usually keeps us in search and copy loop, constantly searching for some snippet without fully understanding how or why. Many times we end up spending a lot of time in frustration when the full solution is hack from four different places and they don't seem to work together.
