JavaScript: Uncaught RangeError
I'm having an error which if I declared this.property instead of this._property. What is the problem here?
Here is the code:
class Persoana {
constructor(prenume, nume, varsta) {
this.prenume = prenume;
this.nume = nume;
this.varsta = varsta;
}
get info() {
return `${this.prenume} ${this.nume}`;
}
set varsta(val) {
console.log(`setter varsta: ${val}`);
this.varsta = val;
}
}
let ray = new Persoana("ray", "stone", 30);
console.log(ray.info);
and I have this error:
Uncaught RangeError: Maximum call stack size exceeded at Persoana.set varsta [as varsta] (practice4.js:25)

When you have a setter for a property, then anything that sets the property will implicitly call the setter — even from within the setter function. When a function directly calls itself unconditionally, you get that stack error.
Generally people use some kind of convention for "companion" properties like that:
set varsta(val) {
console.log(`setter varsta: ${val}`);
this._varsta = val;
}
In that case you also need a getter:
get varsta() { return this._varsta; }
