Don't learn TypeScript by skipping JavaScript fundamentals.

Understand JavaScript first.

1️⃣2️⃣ Learn Package Managers

Modern projects use package managers such as npm.

Understand:

• npm install / npm uninstall / npm update / npm run

Also learn what package.json, package-lock.json, and node_modules are used for.

1️⃣3️⃣ Understand Dependencies

When you install a package, you're adding someone else's code to your project.

Before adding unnecessary dependencies, consider:

• Is it maintained?

• Do I need it?

• Is it trustworthy?

• Is it solving a real problem?

Fewer unnecessary dependencies can make projects easier to maintain.

1️⃣4️⃣ Learn to Read Documentation Efficiently

You don't need to read an entire documentation website.

Learn to find:

Installation / Quick Start / API Reference / Examples / Configuration / Troubleshooting

Then experiment with the relevant feature.

Being good at documentation is a major developer skill.

1️⃣5️⃣ Learn to Finish the Last 20%

Beginners often spend most of their energy building the main feature.

Then stop.

But the final part matters:

Main Feature → Validation → Error Handling → Responsive Design → Testing → Accessibility → Performance → Deployment → Documentation

That's what turns a demo into a portfolio-ready project.
