javascript-oop

This is my javascript project using some OOP concepts.

About

It is highly recommended to start looking at the "index.js" file, there I explain some aspects of my project.

Check below a list of OOP concepts that you will find in this project.

Class

In "Client\Client.js":

class Client {
  // ...
}

Encapsulation

Private attribute in "Employee\Employee.js":

constructor(name, salary, cpf) {
  this._name = name
  // ...
}

Abstraction

Abstract method in "Account\Account.js":

withdraw(value) {
  throw new Error('Abstract methods must be overwritten')
}

Abstract class in "Account\Account.js":

constructor(initialBalance, client, agency) {
  if(this.constructor == Account) {
    throw new Error('You cannot initialize an Abstract class of the type Account')
  }
  // ...
}

Inheritance

In "Account\SavingAccount.js":

class SavingAccount extends Account {
  // ...
}

Polymorphism

In "Account\CheckingAccount.js":

withdraw(value) {
  const tax = 1.1
  return this._withdraw(value, tax)
}

In "Account\SalaryAccount.js":

withdraw(value) {
  const tax = 1.01
  return this._withdraw(value, tax)
}

Interface

In "AuthenticationSystem\AuthenticationSystem.js":

static isAuthenticable(authenticable) {
  return 'authenticate' in authenticable
  && authenticable.authenticate instanceof Function
}
