// v2.0，避免一个for (in)，速度大幅度提高，但graph的构造不如之前优雅，优化了hash，总代码量几乎没有增加，加了点注释。
var ops = ['+7', '/2', '*3', '-5'];
var graph = [
[{e:0,n:1}, {e:1,n:1}],
[{e:0,n:0}, {e:1,n:0}, {e:2,n:2}, {e:3,n:2}],
[{e:2,n:1}, {e:3,n:1}]
]; // 第一维是顶点，第二维是出边，e是边的id，n是指向的顶点。
graph.forEach(function(vex, i){
vex.forEach(function(edge, j){
edge.f = new Function('val', 'return val' + ops[edge.e]); // 把边构造成一个function

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');
