Difference between both method ? Is 2nd method is not the correct way to use? btw both working fine

Question

//Getting current src value of img using event object

var imgSrc = e.target.getAttribute('src');

//Getting current src value of img using event object without getAttribute

var imgSrc = e.target.src;

Answer 1

Better use direct method, more readable and faster response. And old IE8 might not support get/setAttribute.
