The function Object [3]

The function object provides a mechanism for indicating JavaScript code to compile as a function. This is the syntax to use the function object:

functionName = new Function(arg1, arg2, arg3, ..., functionCode)

This is similar to the following:

function functionName(arg1, arg2, arg3, ...) {
   functionCode
}

In the former, functionName is a variable with a reference to the function, and the function is evaluated each time it's used instead of being compiled once.
