Prototype or method?

Question

JavaScript

Hello! I wanted to know how prototype differs from a method that can be created in a constructor?

Answer 1

In the first case, the function will belong to the prototype. Will be created once. Will be common to all instances.
In the second, the function will be owned by the instance, will be created each time.

class MyClass {

constructor() {
  this.constFunc = () => {}
}

methodFunc() {}

}

const e1 = new MyClass
const e2 = new MyClass

e1.constFunc === e2.constFunc // false
e1.methodFunc === e2.methodFunc // true
