When I push an object into an array, it pushes the object and it’s methods too like makeaction(), but I don’t wanna see them inside the array, Is there a way to exclude them
I got this on console
[ Pilot {
makeaction: [Function],
_name: 'Michael',
_lstname: 'Kiddies',
_age: 50,
_weight: 80,
_expyear: 8,
vec:
Car {
_price: 3500000,
_weight: 1300,
_speed: 360,
_power: 650,
_brand: 'Aston Martin',
_model: 'Vulcan',
_torque: 1200,
_person: [Circular] } },
Pilot {
makeaction: [Function],
_name: 'Enzo',
_lstname: 'LaFerrari',
_age: 23,
_weight: 90,
_expyear: 20,
vec:
Car {
_price: 3500000,
_weight: 1200,
_speed: 320,
_power: 750,
_brand: 'Ferrari',
_model: 'FXXK',
_torque: 900,
_person: [Circular] } },
Pilot {
makeaction: [Function],
_name: 'Austin',
_lstname: 'Texas',
_age: 30,
_weight: 56,
_expyear: 2,
vec:
Ship {
_price: 5000000,
_weight: 15000,
_speed: 50,
_power: 7000,
_shipname: 'Evelin Mærsk',
_beam: 20,
_lenghtov: 55,
_person: [Circular] } }]
Also I Want to delete that _person: [Circular] inside the array
These are some of my Classes
Pilot.ts
export class Pilot extends Person implements PersonInterface {
private vec: Vehicle;
private _expyear: number;
constructor(name?, lstname?, age?, weight?, expyears?, vec?: Vehicle) {
super(name, lstname, age, weight);
this.vec = vec;
this._expyear = expyears;
vec.person = this;
}
get expyear(): number {
return this._expyear;
}
set expyear(value: number) {
this._expyear = value;
}
public makeaction = () => {
return this.vec.makeaction();
}
}
Car.ts
export class Car extends Vehicle {
private _brand: string;
private _model: string;
private _torque: number;
constructor(brand?, model?, torque?, weight?, speed?, pow?, price?) {
super(weight, speed, pow, price);
this._brand = brand;
this._model = model;
this._torque = torque;
}
get brand(): string {
return this._brand.trim();
}
set brand(value: string) {
this._brand = value;
}
get model(): string {
return this._model;
}
set model(value: string) {
this._model = value;
}
get torque(): number {
return this._torque;
}
set torque(value: number) {
this._torque = value;
}
public makeaction() {
if (this.person.constructor.name == `Customer`) {
return `The ${this.person.constructor.name} ${this.person.name} ${this.person.lstname} has bought the ${this.constructor.name} ${this.brand + ` ` + this.model} for only ${prf.convertMillions(this.price)}`;
}
else {
return `The ${this.person.constructor.name} ${this.person.name} ${this.person.lstname} is driving the ${this.constructor.name} ${this.brand + ` ` + this.model}`;
}
}
}
Answer
The problem with public makeaction = () => {, and the reason why it shows up in the console, is that it is a class property not a prototype method. It’s a property created in the constructor and assigned an arrow function. You’ll want to make it a normal method:
public makeaction() {
…
That way, it’s implicitly non-enumerable (in ES6 classes at least), and won’t be considered by the console pretty printer because it is inherited.
