Script Preparation code:

function Method(change) { this.change = change; }

Method.prototype = {
    constructor: method,
    getVars: function() {
        if (this.change >= 0) {
        	return {
                color: 'green',

    get color() {
		return this.positive ? 'green': 'red';
    },
}

var method = new Method(1);
var getters = new Getters(1);

Tests:

getter tree
var icon = getters.icon; var color = getters.color;
single method
var allVars = method.getVars(); var icon = allVars.icon; var color = allVars.color;
