There's nothing like "I'm ready to do X right now". We learn by doing and making mistakes. I learned that when I was launching my startup. I knew I needed to learn more... So I sought out mentors and advisors to help me fill the gaps. But I started and learned along the way.

The path from developer to architect is one thing. Going from "I can build this" to "I can decide what to build, how to scale it, and why one architecture beats another." That's the path. And that's what AI cannot replace.

Writing code was never the bottleneck. In a typical sprint, an engineer spends maybe 20% of their time on net-new code. The rest is reading, debugging, reviewing, deciding, communicating, and operating.

How to be mediocre? 🚨 Stop learning. ⚠️ People are getting pleased by their comfort, so they usually miss opportunities to stretch their comfort zone and learn. 💪 Embrace mistakes. 🌱 Grow from failures. 🏃‍♂️ Let’s go to the Growth Zone.

• Junior developer → Delivers a task. • Mid/Regular developer → Delivers a project. • Senior & above developer → Delivers a standard. Senior developers improve the overall velocity of the organization by introducing many practices and standards.

Known vulnerabilities in dependencies. Some versions of third-party components might contain security issues. Check your dependencies and update when better versions become available. ✅ Use a tool like the free Snyk CLI to check for vulnerabilities.

When you start a new project or join an older one, add a `jest watch` command to the package.json. When you run the `test:watch` command, it provides real-time feedback and detailed output of your tests.

Be mindful when you’re looking for your next job… If you go for the earning early, you stop the learning early. Do not think short. Be smart. There’s time for the earning. Skills will compound. In the best case, you will be optimizing for both earning and learning.

State management libraries help manage and centralize state in React applications, which can grow complex as the application scales. However, as they might help, they can also add extra complexity, which might not be necessary and beneficial.

If you don't want to spend 10 minutes reading the documentation, you can always spend 10 hours debugging the issue. 🤷‍♂️ Be mindful of the trade-off and your time. Act appropriately.

Consistency is key in any project. In the JavaScript world, I've found Airbnb's JavaScript Style Guide to be a must-have for every project. Following a style guide in a project offers several benefits: 🧵

One of the best resources I found for learning patterns for improving a website's performance, design, and rendering. Patterns for JavaScript, React, and Vue. It has practical and visual examples.

Always remember the KISS principle when coding. KISS = Keep It Simple, Stupid. The key essence of this principle is: 💡 Don’t add unnecessary complexity to our software.

Code is read-heavy. We spend more time reading existing code than we spend writing new code.

In the busyness and hustle of modern work culture, it’s easy to get caught up in the 24/7 working mode. We often push ourselves to the end, forgetting that we need to step back and recharge to deliver our best.

The organization of files and folders in a React application is crucial for maintaining clarity and manageability. The easier it is to navigate throughout the project, the less wasted time for developers to navigate and wonder where and how to change stuff.

Be careful when using the JavaScript spread operator. 💡 It's a common JavaScript Interview question! The JavaScript spread operator does a shallow copy. Basically, it will deep-copy the top-level elements but shallow-copy the nested ones. See the attached screenshot 👇

In TS v5.5, type predicates are inferred automatically from functions that return a narrowing statement. It’s not necessary to use "x is string" anymore to force TypeScript to infer the proper type. ——— ♻ Repost to help others find it

Instead of being too "smart" in your code, think about your colleagues and future teammates. Maybe it's better to write 2-3 lines more, but guarantee that your future teammates will understand it. Remember: Complexity is a liability; Simplicity is an asset.

Time is the most valuable commodity we have, yet somehow, we give it less importance than money. You can always make more money, but you can never get your time back once it has passed.

Your package.json plays a crucial role in managing a JavaScript project, especially one using Node.js, npm, or yarn. Your package.json defines your project’s dependencies - the external packages and libraries your project relies on to work.

Software development isn’t just about writing code. It’s about making products that solve real problems for real people. If you do it right, your company will be successful. If you do it wrong, you might be looking for a new job. P.S. Repost this ♻️ Someone out there might need it!

A common mistake: "Let's abstract this in case we want to replace it later." Examples: ❌ "Let's abstract Tailwind CSS in case we switch CSS approaches." ❌ "Let's abstract React in case we switch JS frameworks." ❌ "Let's abstract MySQL in case we switch Databases."

3 simple focus areas to level up as a developer: 1. Become a problem-solver. 2. Learn to communicate. 3. Build lots of projects. If you practice these 3 consistently, there's no limit to how great of a developer you'll become.

These 2 simple debugging techniques will save you more time than anything else as a front-end developer: 1. console.log in JavaScript 2. { border: 1px solid red; } in CSS Can't remember the number of times these 2 tricks have saved me many hours of debugging... 👀

When building a React Application, the way you organize and design your code has a tremendous impact. It can either help you and your team find things more easily, make updates quicker, and better manage the app as it grows, or make everything much worse.
