Title: Why The Complete JavaScript Course 2020 Is Still a Must-Take (Even Years Later) Category: Web Development / Course Review Reading Time: 6 minutes

The Intro: Finding the "One" JavaScript Course Let’s be honest. The internet is flooded with JavaScript courses. You have free tutorials on YouTube, expensive bootcamps, and everything in between. Back in 2020, when the demand for modern JavaScript (ES6 and beyond) was exploding, one course rose to the top: "The Complete JavaScript Course 2020: Build Real Projects" by Jonas Schmedtmann on Udemy. Fast forward to today. Is a course labeled "2020" still relevant? The short answer is yes , but let me explain why this specific course is still the gold standard for turning a confused beginner into a confident developer. What Makes This Course Different? Most courses teach you syntax . Jonas teaches you thinking . Here is the breakdown of what you actually get: 1. The "How to Think Like a Developer" Section This is not your typical "Hello World" intro. In the first few hours, Jonas introduces a problem-solving framework. He forces you to pause the video, try to solve a challenge, fail , and then watch his solution. This muscle memory is invaluable. 2. Deep Dives into Weird Parts JavaScript has quirks (hoisting, scoping, the this keyword, prototypal inheritance). Most courses gloss over these. Jonas uses a visual whiteboard to draw the execution context and the call stack. By the time you finish, you won't fear a technical interview question about closures. 3. Modern ES6+ (The 2020 Stack) Even though it says "2020," this course covers:

Arrow functions & Template literals Destructuring & Spread operators Promises, Async/Await (Crucial for modern APIs) Modules (import/export)

Note: Since 2020, new features have come out (Optional chaining, Nullish coalescing, replaceAll ). However, the fundamentals taught here make learning those 2024 updates a 10-minute task. The Real Gold: The 3 Portfolio Projects You don't learn to code by watching. You learn by building. This course uses a project-based approach that forces you to use everything you learned. Project 1: The Pig Game A simple 2-player dice game. You learn DOM manipulation, event handlers, and state management. It’s fun, interactive, and immediately satisfying. Project 2: Budgety (The Expense Tracker) This is the "make or break" project. You will build an MVC (Model-View-Controller) architecture from scratch. You will learn how to separate data logic from UI logic. This is the moment you stop being a "beginner" and start being a "front-end engineer." Project 3: Forkify (Recipe Search App) You build a real-world application using an external API (Recipe API). You will learn: the complete javascript course 2020

Making AJAX calls with fetch and Async/Await Handling loading states and errors Local storage (saving favorite recipes) Building a search engine with pagination

Who Is This Course For?

Absolute Beginners: The pace is perfect, but you must be patient. It is 69 hours long. Bootcamp Grads: If you learned React but don't understand vanilla JS, this fills the massive holes in your knowledge. CS Students: You know theory, but this teaches you practical web app building. NOT for: Someone who wants to learn React, Vue, or Angular. This is pure, framework-less JavaScript (which is exactly what you need before learning frameworks). Title: Why The Complete JavaScript Course 2020 Is

The 2020 Problem: Is it outdated? Let's address the elephant in the room. The course uses var occasionally (to explain why let and const are better). It uses XMLHttpRequest briefly for legacy context, but immediately switches to Fetch . Missing pieces (compared to 2025 standards):

No native ES2022/ES2023 features (Array.at, Object.hasOwn, etc.) No Vite or modern build tooling (It uses Parcel, which is fine, but outdated). No TypeScript (Though Jonas has a separate course for that).

The Verdict: The core 90% of this course is timeless. The event loop, promises, scope, and OOP in JS have not changed. You can finish this course and learn the remaining 10% of new syntax in a weekend. The Verdict: 5/5 Stars The Complete JavaScript Course 2020 is the textbook I wish I had in college. Jonas is a fantastic instructor—his code is clean, his voice is calm, and his explanations are visual. If you buy this course today (on sale, as Udemy always is), ignore the "2020" in the title. Think of it as "The Complete JavaScript Course: Fundamentals through Advanced." Final Advice: Do not skip the coding challenges. Do not copy-paste the final project. If you code along for 69 hours, you will be a job-ready JavaScript developer. Back in 2020, when the demand for modern
