Course content

18 sections • 82 lectures • 9h 56m total length

  • What is Design Patterns?3:00

    Explore how design patterns, from singleton to observer, serve as building blocks of software architecture, providing reusable solutions that keep code maintainable, scalable, and adaptable.

  • Don't reinvent the wheel2:51
  • Object Oriented Design6:04

    Use design patterns to strengthen object oriented design and maintainability. Explore patterns like singleton, factory, and observer from Gang of Four to avoid reinventing the wheel and adapt to change.

  • Categories Of Design Patterns4:01
  • Why Every Developer Needs to Know Design Patterns0:43
  • The Historical Evolution Of Design Patterns in Computing : A Quick Dive0:49
  • Definition Of Antipatterns4:16

    Define antipatterns in software engineering, show why they hinder progress, and reveal how recognizing them leads to cleaner, maintainable code. Use a mental map to navigate design challenges.

  • Congratulations1:24

Requirements

  • No programming experience needed. You will learn everything you need to know
  • Basic Javascript knowledge is good but not must
  • Familiarity with latest JavaScript language features

Description

Are you tired of writing "spaghetti code" that breaks every time you add a new feature?

You know how to write JavaScript, but do you know how to architect it? Transitioning from a junior to a senior developer requires more than just knowing syntax. It requires knowing how to design software that is clean, scalable, and easy to maintain.

Welcome to JavaScript Architecture: Design Patterns & SOLID Principles.

Many developers believe that Object-Oriented Programming (OOP) and Gang of Four (GoF) patterns are only for strict languages like Java or C#. That is a myth. Applying these proven architectural principles to JavaScript is the secret weapon for building robust front-end applications and scalable Node.js backends.

What You Will Learn: This course isn't just theory. We dive deep into practical, real-world JavaScript implementations of the most critical software design concepts in the industry.

1. The SOLID Principles Learn the 5 pillars of scalable architecture and how to apply them specifically in JavaScript:

  • S - Single Responsibility Principle

  • O - Open/Closed Principle

  • L - Liskov Substitution Principle

  • I - Interface Segregation Principle

  • D - Dependency Inversion Principle

2. Creational Design Patterns Master how to create objects the right way:

  • Simple Factory, Abstract Factory, & Factory Method

  • Singleton, Builder, Prototype, & Object Pool

3. Structural Design Patterns Learn how to assemble objects and classes into larger, flexible structures:

  • Adapter (Object & Class), Decorator, & Bridge

  • Facade, Proxy (Static & Dynamic), Flyweight, & Composite

4. Behavioral Design Patterns Control how your objects communicate with each other:

  • Observer, Strategy, Command, & State

  • Chain of Responsibility, Iterator, Mediator, & Memento

  • Template Method, Visitor, & Null Object

5. JavaScript Anti-Patterns (What NOT to do) Knowing what not to do is just as important. We will dedicate an entire section to identifying common JavaScript anti-patterns and refactoring bad code into clean code.

Why Take This Course?

  • No Fluff: We get straight to the point with hands-on, follow-along coding lectures for every single pattern.

  • Modern JavaScript: All examples are written in modern JS, relevant to today's React, Vue, Angular, and Node.js ecosystems.

  • Interview Prep: System design and pattern questions are heavily tested in senior-level tech interviews. This course gives you the vocabulary and knowledge to ace them.

Who Should Enroll?

  • Junior/Mid-Level Developers who want to write cleaner code and level up to Senior positions.

  • Self-Taught Devs & Bootcamp Grads who missed out on traditional Computer Science architecture classes.

  • React/Node.js Developers dealing with messy, hard-to-maintain codebases.

Stop guessing how to structure your apps. Enroll today and start writing JavaScript like a software architect!

Who this course is for:

  • If you are just beginning your career, then you must take this course. It'll benefit you most
  • If you are preparing for interview, this course is a must for you.
  • If you are experience developer, this course will help you brush up your software design skills
  • Software Designers & Architects.
  • If you are a JavaScript developer who is familiar with basic JavaScript syntax, seeking further exposure to real-world object-oriented programming, then this is the course for you!
