learn you node http collect

httpCollect.js

var http = require('http')

var url = process.argv[2]

http.get(url, function (resp) {
    var respContent = ""
    resp.setEncoding('utf8')

    resp.on("data",function (data) {
        respContent += data
    }).on("end", function () {
            console.log(respContent.length)
            console.log(respContent)
        })
})

isnt the " console.log(respContent.length) "

should console.log() the length every time end() callback being called ?
which means more then one ? ?
