Variable not displayed in console.log

here is my code.

let userName = 'dave'
userName = userName ? console.log(`Hello, ${userName}`) : console.log('Hello!')

let userQuestion = 'Am I crazy'
console.log(`${userName} asked: ${userQuestion}`)

expected output

Hello, dave
dave asked: Am I crazy

actual output

Hello, dave
undefined asked: Am I crazy

Why is it showing 'undefined` ?

You are assigning incorrect value in the second line, which makes it undefined.

let userName = 'dave'
//userName = userName ? console.log(`Hello, ${userName}`) : console.log('Hello!')
console.log(userName ? `Hello, ${userName}` : 'Hello!')

let userQuestion = 'Am I crazy'
console.log(`${userName} asked: ${userQuestion}`)

userName = userName ? console.log(`Hello, ${userName}`) : console.log('Hello!')

This line of code changes the content of the variable userName by whatever the console.log() return. And they return undefined

you are trying to assign the console.log to userName and using it. change the code to

let userName = 'dave'
console.log(userName ? `Hello, ${userName}` : 'Hello!');

let userQuestion = 'Am I crazy'
console.log(`${userName} asked: ${userQuestion}`)

or you can use the line as follows.

userName ? console.log(`Hello, ${userName}`) : console.log('Hello!')


let userName = 'dave'
userName ? console.log(`Hello, ${userName}`) : console.log('Hello!');


let userQuestion = 'Am I crazy'
console.log(`${userName} asked: ${userQuestion}`)
