null 为止(也就是不再有原型指向),组成这条链的最后一环。这种一级一级的链结构就称为原型链(prototype chain)。等等node.js1.0 的发布

当你使用Node.js一年以后,你老板让你开发一个Java的项目

var copyFile = function(srcPath, tarPath, cb) {
var rs = fs.createReadStream(srcPath)
rs.on('error', function(err) {
if (err) {
console.log('read error', srcPath)
}
cb && cb(err)
})
var ws = fs.createWriteStream(tarPath)
ws.on('error', function(err) {
if (err) {
console.log('write error', tarPath)
}
cb && cb(err)
})
ws.on('close', function(ex) {
cb && cb(ex)
})
rs.pipe(ws)
}
