javascript - 如何实时显示 Javascript 输出？

Question

如果这是一个简单的问题，我们深表歉意，但是有没有一种方法可以将 Javascript 实时输出到控制台，同时在每次用户交互时暂停。换句话说，如果我做一些像...这样简单的事情

console.log("What's your name: ");
let userName = prompt("What is your name?");
console.log(userName);

console.log("\n");

console.log("Nice to meet you " + userName + "! What is your age?");
let userAge = prompt("What is your age?");
console.log(userAge);

...我可以在年龄提示出现之前将名字输出到屏幕吗？这在其他教学环境(MS Basic 和命令提示符)中是可行的，但要么在 Javascript 中不存在，要么我遗漏了一些东西。

感谢您帮助新人!

你可以使用 setTimeout，像这样:

console.log("What's your name: ");
let userName = prompt("What is your name?");
console.log(userName);

console.log("\n");
setTimeout(function(){
console.log("Nice to meet you " + userName + "! What is your age?");
let userAge = prompt("What is your age?");
console.log(userAge);
},1000)

注意:这是一种方法，还有很多其他方法可以做到。

如果你想使用 promises:

let userName,userAge, userSport;
function basic(){
console.log("What's your name: ");
var promise1 = new Promise(function(resolve, reject){
userName = prompt("What is your name?");
resolve(userName)
})
promise1.then(function(value){
console.log(value);
console.log("\n");
console.log("Nice to meet you " + value + "! What is your age?");
var promise2 =  new Promise(function(resolve, reject){
userAge = prompt("What is your age?");
resolve(userAge)
})
promise2.then(function(value){
console.log(value)
console.log("Nice to meet you " + userName + " aged: " +userAge + ". Let us know your favorite sports")

var promise3 = new Promise(function(resolve, reject){
userSport = prompt("What is your favorite sports?");
resolve(userSport)
})
promise3.then(function(value){
console.log(value)
console.log("Nice to meet you " + userName + " aged:  " +userAge + " and your favorite sports is " +value)
console.log("\n");
console.log("Thanks");
})
})
})

}
basic()
