Create a JavaScript function dynamically with strings

gistfile1.js

// Create the function
// 'a' and 'b' are the arguments available to the function,
// the last string is the body of your new function
var x = Function('a','b','console.log(a+b); return "apples";');

// Implementation
x(1,2); // will return 'apples' and will log to the console '3';
