Top 10 VS Code Extensions That Saved Me Hours Every Week (And Leveled Up My Coding Career)

Dev Nquizi — Thu, 05 Mar 2026 19:12:57 +0000

A few years ago, I used to think being a “good developer” meant typing fast.

I would open Visual Studio Code, write everything manually, fix formatting issues myself, scroll endlessly looking for errors, and constantly switch between tabs to check Git history.

I was busy.

But I wasn’t productive.

At some point, I noticed something interesting: senior developers didn’t necessarily code faster — they coded smarter. Their editors were doing half the work for them.

That’s when I discovered the power of VS Code extensions.

And honestly? It changed everything.

The Turning Point
One day, I installed Prettier.

That single extension removed:

Inconsistent spacing
Debates about semicolons
Manual formatting
Wasted time cleaning code before pushing
I hit “Save”… and my code formatted itself.

That was the moment I realized:
Tools can multiply your productivity.

The Extensions That Transformed My Workflow
Here are the tools that truly made a difference in my journey:

1️⃣ Prettier
Auto-formats your code on save.
No more messy files. No more formatting arguments.

2️⃣ GitLens
Shows who changed what and when — directly inside your editor.
Perfect for collaboration and debugging.

3️⃣ TabNine
AI-powered code completions.
It feels like coding with a smart assistant beside you.

4️⃣ Visual Studio Code Remote — SSH
Edit remote servers as if they’re local.
Game-changer for backend developers.

5️⃣ Live Share
Real-time pair programming.
Ideal for mentoring or team debugging.

6️⃣ Todo Tree
Find all your TODO and FIXME comments instantly.

7️⃣ Code Time
Track how long you actually code.
It helped me understand my focus patterns.

8️⃣ WakaTime
Real-time coding metrics and insights.

9️⃣ Simple Coding Time Tracker
Heatmaps and productivity tracking.

🔟 VSCode Analytics
Local coding insights without complex setup.

What I Learned
Here’s the truth most beginners don’t realize:

Productivity isn’t about working harder.
It’s about removing friction.

Every second you spend:

Formatting code manually
Searching for TODO comments
Switching tabs to check Git history
Guessing how much time you actually code
…is time you could use building real skills.

Extensions don’t replace your knowledge.
They amplify it.

Why This Matters (Especially If You’re Growing as a Developer)
When I started taking coding seriously, especially building projects and sharing content online, I realized something:

Efficiency creates consistency.

And consistency builds growth.

Whether you’re:

A frontend developer
A backend developer
A student learning to code
Or building your personal brand in tech
Your tools matter.

Final Thoughts
You don’t need 50 extensions.
You need the right ones.

Start small:

Install Prettier
Add GitLens
Try one AI assistant
Then build your toolkit intentionally.

Because in tech, the difference between average and exceptional is often hidden in small optimizations.

Master Debugging in JavaScript & React: Avoid These 3 Common Mistakes

Dev Nquizi — Sun, 11 Jan 2026 20:24:42 +0000

Debugging is one of the most important skills for any developer, yet it’s also one of the most challenging. Whether you’re building web apps with JavaScript, React, or working on backend code, understanding why your code breaks can save hours of frustration.

Here are 3 common mistakes beginner developers make when debugging and how to avoid them:

1) Not Reading the Error Message Properly
Error messages aren’t just annoying pop-ups—they’re clues. Many beginners skip over them or only glance at them. Take the time to read the full message, understand which file, line, and function it points to, and research any unfamiliar terms. This small habit will drastically improve your debugging speed.

2) Overlooking Small Typos
Sometimes the bug isn’t in your logic—it’s a tiny typo. Misspelled variable names, missing semicolons, or wrong capitalization can break your code. Always double-check your syntax and consider using a linter in VS Code to catch these mistakes automatically.

3) Trying to Debug Too Much Code at Once
When something breaks, it’s tempting to start changing multiple files at once. Instead, isolate the problem. Test small sections of your code incrementally. This method makes it easier to identify the root cause without introducing new bugs.

Debugging is a skill that improves with practice. By avoiding these mistakes, you’ll spend less time frustrated and more time building amazing applications.
