Related to class fields

[vivek1394Git]

Hello there,
It is written in class field section(https://javascript.info/class):
"Technically, they are processed after the constructor has done it’s job, and we can use for them complex expressions and function calls:
`class User {
name = prompt("Name, please?", "John");
}

let user = new User();
alert(user.name); // John`
"

I've checked it using this code.
`class User {
name = prompt("Name, please?", "John");
constructor() {
alert("I was here later!");
}
}

let user = new User();
alert(user.name); // John`

And as I had expected "prompt" was called before "alert", because I think "Class fields are processed before constructor."
I've been learning from your awesome tutorials since some days and they are really awesome.
I want to thank you for these awesome articles!!!

Please re-read: "Technically, they are processed after the constructor"

[vivek1394Git]

If they are processed after then why prompt is prompted before alert in the constructor?

[iliakan]

prompt is processed immediately, but name = - only after constructor.

Please take a look at this article from proposal.
https://github.com/tc39/proposal-class-fields#execution-of-initializer-expressions

When field initializers are evaluated and fields are added to instances:
Base class:" At the beginning of the constructor execution", even before parameter destructuring.

Thank you!

Please don't look at the proposal. The proposal is irrelevant.

Look at the specification instead.

Could you please look at this code!
`class User {
constructor() {
alert(this.name) // this works
//constructor is still executing....
}
name = "Name"
}

let user = new User();`

Tomorrow I'll add more details about that.

Indeed, not well-explained.
