struggling with utilizing JSON.stringify()

Question

struggling with utilizing JSON.stringify()

I have been attempting to log an object's attributes using console.log(JSON.stringify(object)) in TypeScript and then converting it to JavaScript. However, when I call the function, nothing gets logged. I am creating the object with the parameters of the class. Here is the code snippet:

*class app{
    constructor ( file: string ){}
}
function createApp(){
    let v = new app ( 'image 2');
    console.log(JSON.stringify ( v ) );
}
createApp();*

Your assistance on this matter would be greatly appreciated.

Answer №1

Here is the code that will display {"file":"image 2"}:

class application {
    constructor(private file: string) {}
}
function generateApp(){
    let var = new application ( 'image 2');
    console.log(JSON.stringify ( var ) );
}
generateApp();

However, for object serialization purposes, I suggest the following modification to make it clearer:

class Application {
    constructor(private file: string) {}

    public serialize() {
         return JSON.stringify({ file: this.file });
    }
}

function createApplication(){
    let var = new application ( 'image 2');
    console.log(var.serialize());
}

createApplication();
