if/else 语句似乎在 Javascript 中不起作用，我不知道我做错了什么

Question

I am struggling to get this to work for a Javascript magic 8 Ball, and for the life of me i cannot figure out what the issue is, so i am hoping someone on here will be able to tell me what I am doing wrong. I will pose the code as it is now:

let userName = "Vince";
if (userName === true){
  console.log(`Hello ${userName}`);
} else {
  console.log(`Hello!`);
}
let userQuestion = "";
if (userName === true){
  console.log(`${userName},You asked me \"${userQuestion}\"`);
} else {
  console.log(`You asked \"${userQuestion}\"`);
}

I have also tried

let userName = "";
userName === true
  ? console.log(`Hello ${userName}`)
  : console.log("Hello!");
let userQuestion = "";
userName === true
  ? console.log (`${userName},You asked me \"${userQuestion}\"`)
  : console.log(`You asked \"${userQuestion}\"`);

No matter what i do here, it will only ever run the "else" section of code so i am getting this:

Hello! You asked "will i win the lottery" It is decidedly so

I have no doubt that the answer is obvious and I am being dense, or i have just misunderstood something about truthy/falsey statements, but i am very close to pulling my hair out at this stage, so any help you can offer would be greatly appreciated.

i have switched the above around and tried loads of different things. Just a bit lost.

Answer 1

You are trying to compare two different data types: userName is a String, while true is a boolean value, that is why the if condition is never satisfied.

The correct way to check for userName would be:

    if (userName){
console.log(`Hello ${userName}`)
} else{
console.log(`Hello!`)
}

Answer 2

Your fault lies in the datatype youre checking. You expect a bool but your are giving it a string.

I assume you want to check if there is a name and not empty?

let userName = "Vince"

if (!!userName){ //Checks if username is not empty.
console.log(`Hello ${userName}`)
} else{
console.log(`Hello!`)
}```
