Observables

You don't really need a framework or fancy cutting-edge JavaScript features to do two-way data binding. Let's start basic - first and foremost, you need a way to tell when data changes. Traditionally, this is done via an Observer pattern, but a full-blown implementation of that is a little clunky for nice, lightweight JavaScript. So, if native getters/setters are out, the only mechanism we have are accessors:

var n = 5;
function getN() { return n; }
function setN(newN) { n = newN; }

console.log(getN()); // 5

setN(10);

JSON Puller - Google Apps Script

Transforms the data of a given Spreadsheet Sheet to JSON.

The frozen rows are taken as keys for the JSON.
The data taken for the values is only that after the frozen rows

Set up:

exportJSON(Spreadsheet) - transforms the data in the given sheet to JSON.

	//Example 1 - Calculate average value of an array (transform array into a single number)
	var scores = [89, 76, 47, 95]
	var initialValue = 0
	var reducer = function (accumulator, item) {
	return accumulator + item
	}
	var total = scores.reduce(reducer, initialValue)
	var average = total / scores.length
