I Learned React. Then I Realized I Wasn't Learning Frontend Engineering.
felix asante · 2026-06-18 · via DEV Community

felix asante

A few years ago, I thought React was the key to becoming a frontend developer.

So I did what most beginners do.

I bought courses.
I watched YouTube tutorials.
I built apps.
I learned hooks.
I followed along with project videos.

I felt productive.

Then I started applying for jobs.

That's when reality hit.

Interviewers weren't interested in whether I knew useState or useEffect.

They asked questions like:

  • What happens when you type a URL into a browser?
  • Can you explain closures?
  • Why is this component re-rendering?
  • How would you improve this page's performance?
  • How do you make this form accessible?
  • What testing strategy would you use here?

I quickly realized something:

I had learned React.

I had not learned frontend engineering.

The Problem With Most Learning Paths

Most frontend tutorials teach tools.

Very few teach engineering.

You'll find hundreds of videos showing you how to build a Netflix clone.

But almost none explain:

  • Why browsers render pages the way they do
  • How caching works
  • What causes layout shifts
  • Why accessibility matters
  • How to write maintainable code
  • How to test effectively
  • How to debug production issues

As a result, many developers spend months learning frameworks while ignoring the fundamentals that employers actually care about.

The Five Biggest Mistakes I Made

1. Consuming More Than Building

Watching tutorials feels productive.

Building from scratch feels uncomfortable.

Unfortunately, growth happens in the uncomfortable part.

The projects that taught me the most were the ones where there was no tutorial to follow.

2. Ignoring JavaScript Fundamentals

React became significantly easier once I deeply understood:

  • Closures
  • Scope
  • Hoisting
  • The Event Loop
  • Async programming
  • Reference vs value

Many React problems are actually JavaScript problems.

3. Building Portfolio Projects Nobody Cared About

My portfolio contained:

  • Netflix clone
  • Expense tracker app
  • Calculator apps

Recruiters had already seen thousands of them.

What stood out later were projects that demonstrated:

  • Authentication
  • API integrations
  • State management
  • Testing
  • Performance optimization
  • Real-world problem solving

4. Treating Accessibility and Performance as Advanced Topics

I used to think accessibility and performance were things I'd learn later.

The truth is they're part of frontend development.

A slow application is a bug.

An inaccessible application is a bug.

5. Applying Without a System

For months, I randomly applied for jobs.

No strategy.
No process.
No feedback loop.

Eventually, I learned that getting hired requires more than coding skills.

You need:

  • A strong portfolio
  • A clear resume
  • Interview preparation
  • Communication skills

What I Would Do Differently Today

If I had to start over from scratch in 2026, I would focus on:

Month 1–2

  • HTML
  • CSS
  • JavaScript Fundamentals
  • Git
  • Building simple projects

Month 3–4

  • TypeScript
  • React
  • API integration
  • Testing basics

Month 5

  • Next.js
  • Accessibility
  • Performance optimization

Month 6

  • Advanced projects
  • Portfolio refinement
  • Interview preparation

Most importantly:

Spend 20% of your time learning and 80% building.

That ratio changed everything for me.

Final Thoughts

The goal isn't to learn React.

The goal isn't to complete courses.

The goal is to become capable of building real products and solving real problems.

Frameworks will change.

Libraries will change.

The fundamentals won't.

Focus on becoming an engineer first.

The tools will follow.

I eventually organized everything I wish I'd known into a structured 24-week roadmap called The Frontend Engineer's Playbook 2026.

It includes project roadmaps, learning paths, portfolio guidance, interview preparation, and curated resources for aspiring frontend engineers.
