as == in JavaScript is used for comparing two variables, but it ignores the datatype of variable, gives true here,

"abc"=="abc"
true

gives false here,

new String("abc")==new String("abc")
false

but this still why output is coming as false, as value of both is same abc string object, as javascript have new datatype of Symbol,

Symbol("abc")==Symbol("abc")
false
Symbol(new String("abc"))==Symbol(new String("abc"))
false

whats difference in both, what should be used in which scenarios, why both gives sameoutput?
