Quick Answer: How to Learn TypeScript on Scrimba (2026 Guide). See below for full details.
Last reviewed: March 2026.
TypeScript has gone from "nice to have" to "required" in the web development world. Most React job postings now list TypeScript as a requirement, and major frameworks like Next.js, Angular, and NestJS are TypeScript-first.
This guide covers how to learn TypeScript using Scrimba's courses, what order to take them in, and how to apply TypeScript to your projects.
Who This Is For
Readers interested in this topic.
Why Learn TypeScript?
TypeScript adds static types to JavaScript. This means:
- Bugs caught before runtime — the compiler tells you about errors before users see them
- Better IDE experience — autocomplete, refactoring, and inline documentation
- Easier collaboration — types serve as documentation for your team
- Required by employers — most frontend and fullstack job listings mention TypeScript
Learning Path: JavaScript First, Then TypeScript
You need solid JavaScript fundamentals before TypeScript makes sense. Here's the recommended order on Scrimba:
Step 1: JavaScript Fundamentals (Free)
Learn JavaScript — 9 hrs
Start here if you're new to programming. Covers variables, functions, arrays, objects, DOM manipulation, and async JavaScript. This is free and gives you the foundation TypeScript builds on.
Step 2: Build React Skills (Free)
Learn React — 15.1 hrs
React and TypeScript are a powerful combination. Learning React first (in JavaScript) lets you focus on component patterns, hooks, and state management without the added complexity of types.
Step 3: Learn TypeScript (Pro)
The core TypeScript course covering: basic types, interfaces, generics, type narrowing, utility types, and TypeScript configuration. Interactive format means you're writing typed code from the first lesson.
Step 4: Apply TypeScript to Projects
Take your React projects and convert them to TypeScript. This is where the learning really sticks. Practice typing:
- Component props and state
- API response objects
- Event handlers
- Custom hooks
TypeScript Skills You Need for Jobs
Based on job postings, these are the TypeScript skills employers look for:
Must-Have
- Basic types — string, number, boolean, array, object
- Interfaces and type aliases — defining object shapes
- Generics —
Array<T>,Promise<T>, custom generic functions - Union types —
string | number, discriminated unions - Type narrowing — typeof, instanceof, and type guards
Nice to Have
- Utility types —
Partial<T>,Required<T>,Pick<T>,Omit<T> - Mapped types — creating new types from existing ones
- Conditional types —
T extends U ? X : Y - Declaration files — writing .d.ts files for untyped libraries
Advanced (Senior Roles)
- Template literal types — type-safe string manipulation
- Infer keyword — extracting types from generic patterns
- Module augmentation — extending third-party type definitions
Common Mistakes When Learning TypeScript
- Using
anyeverywhere — this defeats the purpose. Challenge yourself to find the right type. - Over-typing — TypeScript can infer many types. Don't annotate what the compiler already knows.
- Ignoring errors — TypeScript errors are informative. Read them carefully instead of adding
// @ts-ignore. - Not using strict mode — always enable
"strict": truein tsconfig.json for the full benefit.
TypeScript in the Job Market (2026)
TypeScript demand continues to grow:
- React + TypeScript is now the default for new projects at most companies
- Next.js (the most popular React framework) is TypeScript-first
- NestJS (Node.js framework) requires TypeScript
- AI engineering tools increasingly ship TypeScript SDKs
Learning TypeScript isn't optional anymore — it's the industry standard.

JavaScript first. TypeScript is a superset of JavaScript, so you need to understand the base language. Start with Scrimba's free Learn JavaScript course, then add TypeScript.
If you know JavaScript, basic TypeScript takes 1-2 weeks. Becoming confident with generics, utility types, and advanced patterns takes 4-6 weeks of regular practice.
TypeScript adds a learning curve (type syntax, generics, type errors), but it makes your code easier to write long-term. The compiler catches bugs you would otherwise discover in production.
