准备学 ruby 的前端，还在下 ubuntu。先随便写写

challenge #1 easy

// Create a program that will ask the users name and username, age. have it tell them the information back, in the format
const fs = require('fs')
const readline = require('readline')
let name, age, username, text
let rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
})
function puts(str, callback) {
    rl.question(str + '\n', (answer) => {
        callback(answer)
    })
}
puts('your name?', (answer) => {
    name = answer
    puts('your age?', (answer) => {
        age = answer
        puts('your username?', (answer) => {
            username = answer
            text = ` Your name is ${name}\n You are ${age} old \n Your username is ${username}`
            fs.writeFile('./test.txt', text, function (err) {
                if (err) {
                    throw err;
                }
                console.log(text)
                rl.close()
            })
        })
    })
})
rl.on("close", () => {
    process.exit(0)
})

这种一般都是自己写吧，需求不复杂的话其实就是一个特殊一点的表单。控件用 ui 框架里的就好了
