/*
    * Error - base type for all errors. Never actually thrown by the engine.
    * EvalError - thrown when an error occurs during execution of code via eval()
    * RangeError - thrown when a number is outside the bounds of its range. For example, trying to create an array with -20 items (new Array(-20)). These occur rarely during normal execution.
    * ReferenceError - thrown when an object is expected but not available, for instance, trying to call a method on a null reference.
    * SyntaxError - thrown when the code passed into eval() has a syntax error.
    * TypeError - thrown when a variable is of an unexpected type. For example, new 10 or "prop" in true.
    * URIError - thrown when an incorrectly formatted URI string is passed into encodeURI, encodeURIComponent, decodeURI, or decodeURIComponent.


    if (E instanceof TypeError){
        //handle the error
    } else if (E instanceof ReferenceError){
        //handle the error
