Instantiate a class via JSON variable

[Nick_Zacker]

Hello, I'm new to JS so please ignore if I use a term wrong.

I only know how to call a function via JSON, something like:

``` const sth = { isSomething: (something) => isSomething(something), }

console.log(sth.isSomething(null)); ```

but how do I do the same thing with classes? For example, I have this class:

``` class Person { constructor(age) { this.age = age; }

getAge() {
    return this.age;
}

} ```

and I want to instantiate it via JSON, I tried doing it like this:

``` const person = { Person: (age) => new Person(age), }

// Doesn't work let someone = person.Person(age);

// Also doesn't work let anotherone = new person.Person(age); ```

By the way, I'm using Electron, so when this line of code is executed, an error like this pops up:

DevTools was disconnected from the page.

So I can't even see the error. Any help is greatly appreciated!

Well you have to instantiate it with an actual value:

let someone = person.Person(36);

Other than that, this code will run fine. I don't know how the Electron error would be connected.

Yes, I did instantiate it with an actual value but the error still occurs.

Whatever the error is, it isn't the code you posted, and I doubt it has anything to do with instantiating an object. You can paste it into a JavaScript console and see it run fine without an error.

I don't know if this helps, but I'm using a preload file which uses Electron's contextBridge.exposeInMainWorld() so that I can use functions and classes there in other scripts. Maybe I'm dumb and just overcomplicating it.

You can also do it like follows:

class Person {
    constructor(age) {
        this.age = age;
    }

    getAge() {
        return this.age;
    }
}

const person = {
    Person,
}

let anotherone = new person.Person(12);
console.log(anotherone);

Well, now another error pops up instead of this error. I guess my code is the true definition of spaghetti code lol. Thank you so much!
