hiiii folks

I have a doubt on EL evaluation technique. Please anybody explain me how el evaluates the expression when it's inside quotes "" and without quotes sorrounded.

for ex i saw a quiz

${"a"<"b"} returns true

${a<b} returns false. how?


thanks in advance>

Those aren't brackets, they're quotes.

Think about it: what does a string look like in EL? What does a variable reference look like?
