随机生成二叉树

	function generate(max) {
	var counter = 0;
	var density = 0.7;

	var queue = [];
	function gen(node) {
	node.value = counter++;
	if (counter >= max) return; // this is buggy. may cause real node count > max because it was already generated to the queue.
	if (Math.random() < density) {
	queue.push(node.left = {});

	this.stack = [root];
	this.__pushLeft(root);
	};
	MidIterator.prototype.__pushLeft = function(node) {

LiuJi-Jim / string.format.js

Created November 6, 2014 12:19

Something like String.Format in C# but much more simple.

	function format(fmt){
	var args = Array.prototype.slice.call(arguments, 1);
	for (var i=0; i<args.length; ++i){
	var reg = new RegExp('([^\\\\]\|^)(?:\\{' + i + '\\})', 'g');
	fmt = fmt.replace(reg, '$1' + args[i]);
	}
	return fmt;
	}

	console.log(format('Hello, {0}!', 'world', 'jim'));

LiuJi-Jim / flatten.js

Created August 14, 2014 13:31

LinkedList flatten

	// 极其弱的版本，对于[1, [], 2]这样的奇怪情况（嵌套的是空链）会跪，回头修回头修

	var ListNode = function(value, next){
	// 虽然是简单结构，但是为了Hidden Type优化做成个class
	this.value = value;
	this.next = next;
	};

	var LinkedList = function(){
	this.head = this.tail = new ListNode(null, null);

LiuJi-Jim / app.js

Created August 14, 2014 13:18

express.js auto route，遍历controllers目录里的所有js文件，对里面每个module的每个属性都当做一个/:controller/:action，作自动路由（就跟ASP.NET MVC差不多啦！）

	// app.js
	for (var controller in routes){
	var mod = routes[controller];
	app.all('/' + controller + ':action', function(req, res){
	var action = req.params.action;
	if (action in mod){
	mod[action](req, res);
	}else{
	res.statusCode = 404;
	res.send('404 not found');
