what are route handler in express code example
Example 1: route parameter in node
var express = require('express');
var fs = require('fs');
var app= express();
app.get('/index/profile/:id',function(req,res){
});
app.listen(3000,'127.0.0.1');
console.log('lsitng');
Example 2: express() vs express.router()
var express = require('express'),
dogs = require('./routes/dogs'),
cats = require('./routes/cats'),
birds = require('./routes/birds');
var app = express();
app.use('/dogs', dogs);
app.use('/cats', cats);
app.use('/birds', birds);
app.listen(3000);
