checked = “checked” vs checked = true

Question

What is the difference between the below two usages?

document.getElementById(\'myRadio\').checked = \"checked\";

and

docum         


        

Answer 1

checked attribute is a boolean value so "checked" value of other "string" except boolean false converts to true.

Any string value will be true. Also presence of attribute make it true:

You can make it uncheked only making boolean change in DOM using JS.

So the answer is: they are equal.
