Different ways of accessing attribute values using javascript

Question

document.getElementById(\'myId\').style;

is one way of accessing the style attribute.. Also we can do the same using document.getElementById

Answer 1

there is no difference.

document.getElementById('myId').style;

is a shorthand for

document.getElementById('myId').getAttribute('style');

the only use for getAttribute('attributeName') would be if attributeName is not a valid javascript variable name, so encapsulating it in quotes would be the only way to access it.
