What is the difference between JSP-EL and JSF-EL?

JSP-EL
JSF-EL
In JSP-EL the value expressions are delimited by ${…}.
In JSf-EL the value expressions are delimited by #{…}.
The ${…} delimiter denotes the immediate evaluation of the expressions, at the time that the application server processes the page.
The #{…} delimiter denotes deferred evaluation. With deferred evaluation ,the application server retains the expression and evaluates it whenever a value is needed.
