Those are not quite the same thing. For example:
x = {};
if( x ) alert( 'x' ); // will alert
if( x == true ) alert( 'x == true' ); // will NOT alert
But your point is correct that you don't need to use '== true', except in
the rare case where you actually want to distinguish 'true' itself from
other 'truthy' values. And in that case you'd probably want to use '===
true' to avoid JavaScript's type coercion.
