Function expression is another syntax for creating a function in JavaScript.
Function expression can be stored in a variable. They are always invoked (called) using variable name.
Function name can be omitted in function expressions to create "anonymous" functions.
Function expressions are NOT hoisted in JavaScript, unlike function declarations. It will throw an "ERROR" TypeError: notHoisted is not a function.
