Using JSON.stringify in conjunction with TypeScript getter/setter

Question

I am using getter/setter accessors in TypeScript. As it is not possible to have the same name for a variable and method, I started to prefix the variable with a lower dash,

No, you can't have JSON.stringify using the getter/setter name instead of the property name.

But you can do something like this:

class Version {
    private _major: number;

    get major(): number {
        return this._major;
    }

    set major(major: number) {
        this._major = major;
    }

    toJsonString(): string {
        let json = JSON.stringify(this);
        Object.keys(this).filter(key => key[0] === "_").forEach(key => {
            json = json.replace(key, key.substring(1));
        });

        return json;
    }
}

let version = new Version();
version.major = 2;
console.log(version.toJsonString()); // {"major":2}
