Static class methods are defined on the class itself.
You cannot call a static method on an object, only on an object class.
Example
class Car {
constructor(name) {
this.name = name;
}
static hello() {
return "Hello!!";
}
}
const myCar = new Car("Ford");
// You can call 'hello()' on the Car Class: document.getElementById("demo").innerHTML = Car.hello(); // But NOT on a Car Object: // document.getElementById("demo").innerHTML = myCar.hello(); // this will raise an error.If you want to use the myCar object inside the static method, you can send it as a parameter:
Example
class Car {
constructor(name) {
this.name = name;
}
static hello(x) {
return "Hello " + x.name;
}
}
const myCar = new Car("Ford");
document.getElementById("demo").innerHTML = Car.hello(myCar);
