javascript Expressions code example

Example 1: javascript expressions

An expression is any valid set of literals, variables, operators, and 
expressions that evaluates to a single value. The value may be a number, 
a string, or a logical value. Conceptually, there are two types of 
expressions: those that assign a value to a variable, and those that 
simply have a value.
