Javascript: IE Detection
// ----------------------------------------------------------
// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
// ie === undefined
// If you're in IE (>=5) then you can determine which version:
// ie === 7; // IE7
// Thus, to detect IE:
// if (ie) {}

What is practical difference between String(...) and new String(...)
I failed to properly understand the way String(..) works in following portion:
return new TextCell(String(row[name]));
from http://eloquentjavascript.net/06_object.html
The answer is below https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String:
Distinction between string primitives and String objects
Note that JavaScript distinguishes between String objects and primitive string values. (The same is true of Boolean and Numbers.)

Implement getters and setters to ease access to private members of Vector.
/*global console: true */
"use strict";
/*
A vector type
Write a constructor Vector that represents a vector in two-dimensional
space. It takes x and y parameters (numbers), which it should save to
properties of the same name.
Give the Vector prototype two methods, plus and minus, that take another vector as a parameter and return a new vector that has the sum
or difference of the two vectors’ (the one in this and the parameter) x
and y values.
