${exp} is the general syntax for any EL expression. In case if you want to escape the evaluation, like in a tutorial where you want some expressions to be evaluated and some to be displayed as is. In those places you use any one of the following syntax to escape the EL expression.


Once you escape the starting ${ of the EL expression, the rest of what follows it, will not be evaluated.
