Explanation |

Simpler form for JSP Expressions came with JSTL 1.0, in the form of Expression Language. EL is used to set action
attribute values from different sources at runtime. JSP Expression Language is also used without parameters but as
actions directly in a webpage.
JSP EL always starts with a "$" followed by a "{" and ends with a "}". The expression is specified
inside the brackets. A set of implicit variables provide access to the requested data.
Example:
${2+3+4}
JSP EL supports literal numbers, the boolean value "true,false", "null", the strings
enclosed in single and double quotes.
