Best Free TypeScript Courses [2026]

TypeScript stopped being optional. In the State of JavaScript 2025 survey, 40% of developers said they now write exclusively in TypeScript, up from 34% in 2024, while the share writing only plain JavaScript has shrunk to a small minority. Stack Overflow's 2025 survey tells the same story: TypeScript sits among the languages developers most want to keep working with.

If you write JavaScript for a living, or want to, that makes TypeScript a baseline skill rather than a bonus. The good news is that you can learn it without paying anything.

The bad news is that most "free TypeScript course" lists are noisy. Some entries are paid courses wearing a free-trial costume. Some hand you the lessons but lock the certificate behind a subscription. Some are a one-hour syntax tour that ends before generics, React, or a single real project.

This guide ranks six genuinely free TypeScript courses for 2026, judged on depth, interactivity, projects, certificate, and how current the material is. No paywalled "free trials" pretending to be free.

Best Free TypeScript Courses Ranked for 2026

Six free TypeScript courses, reviewed and ranked by how much they teach, how you learn it, and what you can show at the end. Each entry follows the same shape so you can compare directly.

Scrimba: Learn TypeScript

Best for: Hands-on learners who want to type real code alongside the instructor, not just watch.

Scrimba's Learn TypeScript is 4.2 hours of interactive content split into three modules: TypeScript Fundamentals, TypeScript in React, and TypeScript in Express. It finishes with a solo project, Typed Tenzies, where you add types to a real app instead of a toy snippet. Coverage runs through basic types, interfaces, unions, generics, narrowing, and utility types.

What separates it from the rest of this list is the format. Scrimba courses are scrims, interactive screencasts where you pause the instructor's recording at any line and edit the code directly in the browser. There is no separate editor to wire up and no video-to-IDE context switching. You read a type error, fix it in place, and keep moving.

It is also free in the way that matters most for a "free" list: the completion certificate is included and shareable to LinkedIn, not held back for paying users. For a structured, project-anchored TypeScript course taught by two experienced instructors, 4.2 hours of fully interactive content is a strong free baseline.

Skip if: you want to work in a local VS Code setup from day one. The scrim format runs in the browser and is built for a desktop or laptop, not a phone.

Total TypeScript: Beginner's TypeScript

Best for: Learners who want to build real intuition for how the type system thinks.

Beginner's TypeScript is a free 18-exercise tutorial from Matt Pocock, one of the most recognized TypeScript educators working today. Each exercise gives you a broken or untyped snippet, asks you to fix the types yourself, then walks through the solution. The focus is the why: how inference works, when to reach for a generic, how narrowing changes a type.

It is short and sharp rather than comprehensive. You will not build a full app here, and there is no certificate. What you get is the mental model that makes the rest of TypeScript click, which is exactly the part most beginners skip.

Not for you if you want a complete project sequence. The deeper Total TypeScript material is a paid product; this tutorial is the free on-ramp.

freeCodeCamp: TypeScript Full Course

Best for: Learners who prefer one long, free video to work through at their own pace.

freeCodeCamp publishes full-length TypeScript courses on its YouTube channel for free, including a roughly five-hour beginner course. Coverage is broad: type inference, type aliases, unions, tuples, enums, classes and access modifiers, generics, and discriminated unions with exhaustiveness checking.

The limits are the limits of video. There are no inline exercises, no IDE integration, and no automatic grading. You need your own setup, an editor and the TypeScript compiler, to follow along, and it is easy to watch passively and absorb less than you think. There is no certificate.

Skip if: you suspect you will watch without coding along. A passive five hours teaches far less than an interactive two.

Codecademy: Learn TypeScript (Free Tier)

Best for: Learners who like text-based, auto-graded exercises in a polished browser IDE.

Codecademy's Learn TypeScript is free for the lesson content and runs in Codecademy's browser-based IDE with instant feedback. The syllabus covers types, functions, complex and union types, type narrowing, and advanced object types across about ten hours of material.

The honest catch is the certificate. Codecademy's certificate of completion requires a paid plan, which runs $39.99 per month on the monthly plan ($19.99 per month billed annually). The free lessons themselves are genuinely usable, but if a certificate matters to you, this is not the free option for it.

Skip if: you want the certificate included. The lessons are free; the credential is not.

The Official TypeScript Handbook

Best for: Learners who want the canonical source, straight from the people who build the language.

The official TypeScript Handbook is the free reference maintained by the team behind TypeScript at Microsoft. For someone coming from JavaScript, the "TypeScript for JavaScript Programmers" entry path is the fastest way in, followed by chapters on everyday types, narrowing, functions, object types, classes, and generics.

It reads like a well-written manual, not a course. There is no sequence of milestones and no projects. What it offers is authority: when a tutorial and a Stack Overflow answer disagree, the Handbook is the tie-breaker.

Not the place to start if you want guided, hand-held lessons. The Handbook is documentation, best used alongside a course rather than instead of one.

Exercism: TypeScript Track

Best for: Learners who know the basics and want focused practice with human feedback.

The Exercism TypeScript track is a free, ad-free practice platform with over 100 progressively harder exercises. You solve each in your own editor, submit your solution, and can request feedback from a volunteer mentor who suggests more idiomatic approaches.

Exercism is not a course. There is no instructor, no project sequence, and no certificate. It is a coding gym: a steady supply of small problems with solution discussions once you have solved them. It pairs naturally with a structured course, where the course teaches and Exercism drills.

Skip if: you are starting from zero. Exercism assumes you already know the basics it expects you to apply.

Free TypeScript Courses Compared

The table below ranks each option on the things that actually matter when you are choosing a free course: real cost, whether you build anything, and whether a certificate is included.

Of the six, three are guided learning experiences with feedback (Scrimba, Total TypeScript, Codecademy). One is a long-form video course (freeCodeCamp). One is reference documentation (the Handbook), and one is a pure practice tool (Exercism). Most learners do best combining one guided course with the Handbook as a reference.

What Should a Good Free TypeScript Course Teach?

A free TypeScript course is worth your time when it moves past syntax into the type system's real value: catching mistakes before they ship. The minimum coverage to look for in 2026:

• Basic types, type annotations, and type inference
• Interfaces and type aliases
• Union types and type narrowing, the everyday workhorses of real TypeScript
• Generics, including how and when to reach for them
• Typing functions, objects, and arrays
• Utility types (Partial, Pick, Record, and friends)
• TypeScript with a framework, usually React, plus at least one project where you add types to a real app

A free TypeScript course that stops at adding : string to a variable and never reaches generics or framework typing is a syntax tour, not a course.

That distinction matters because the hard part of TypeScript is not the annotations, it is using the type system to model real code. The official Handbook is the source of truth for what counts as current syntax, so when a course and an old blog post disagree, trust the Handbook.

How to Choose the Right Free TypeScript Course

The right free TypeScript course depends on how you learn and what you want at the end. Four common scenarios:

• Want guided, interactive learning with a free certificate? Scrimba's Learn TypeScript (4.2 hours, interactive scrims, Typed Tenzies project, free certificate).
• Want to understand how the type system actually thinks? Total TypeScript's Beginner's TypeScript is the sharpest free on-ramp.
• Prefer reading and reference over video? The official TypeScript Handbook.
• Already know the basics and want reps? The Exercism TypeScript track.

These resources complement each other. A common path: take one structured course like Scrimba's Learn TypeScript, keep the Handbook open as a reference when you get stuck, then drill on Exercism to make the patterns automatic.

What to Learn After a Free TypeScript Course

Finishing a free TypeScript course is a checkpoint, not the finish line. The steps that matter most next:

• Shore up JavaScript first if it is shaky. TypeScript is JavaScript with types, so weak fundamentals show up fast. Scrimba's free Learn JavaScript (9.4 hours, Per Borgen) is the prerequisite many learners skip and later regret.
• Learn React with TypeScript. Most React job postings now expect TypeScript. Scrimba's free Learn React (15.1 hours, Bob Ziroll) pairs cleanly with a typed setup, and Learn TypeScript already includes a TypeScript-in-React module.
• Move to a structured path. When the free courses run out, Scrimba's Frontend Developer Path is the MDN-aligned route to job-ready, with TypeScript taught in context alongside React and the rest of the frontend stack. Pro is $24.50 per month on the annual plan ($294 per year), or $49 per month monthly, with region-based and student discounts available.
• Or go deeper into the language underneath. Scrimba's Advanced JavaScript (9.8 hours, Pro, Tom Chant) strengthens the JavaScript that TypeScript sits on top of.

The pattern that works: learn free until you outgrow it, then pay for structure when a guided path saves you more time than it costs.

Frequently Asked Questions

What is the best free TypeScript course in 2026?

Scrimba's Learn TypeScript is the strongest free interactive option: 4.2 hours of scrims where you pause and edit the instructor's code in the browser, three modules including TypeScript in React, a typed solo project, and a free completion certificate. Total TypeScript's Beginner's TypeScript is the best free tutorial for type-system intuition.

Can I learn TypeScript for free?

Yes. The free TypeScript ecosystem is excellent. Scrimba, Total TypeScript, freeCodeCamp, Codecademy's free tier, the official Handbook, and Exercism together cover guided courses, intuition-building tutorials, reference docs, and practice, enough to take a JavaScript developer to comfortable TypeScript at no cost.

Do I need to know JavaScript before learning TypeScript?

Yes. TypeScript is a typed superset of JavaScript, so it assumes you already understand variables, functions, arrays, objects, and async code. If your JavaScript is shaky, learn or refresh it first. A free JavaScript course is the right starting point before any TypeScript material.

How long does it take to learn TypeScript?

For a developer who already knows JavaScript, the core of TypeScript takes a few weeks of consistent practice. A focused course like Scrimba's Learn TypeScript is 4.2 hours of instruction and typically takes one to two weeks with practice. Mastering advanced types and generics in real projects takes longer.

Is a free TypeScript certificate worth anything?

A free completion certificate, like the one Scrimba includes, signals that you finished a course and is shareable to LinkedIn, but it is not an accredited qualification. In hiring, the typed projects you build matter far more than the certificate itself. Treat certificates as a small bonus, not the goal.

Key Takeaways

• The strongest free interactive TypeScript course in 2026 is Scrimba's Learn TypeScript: 4.2 hours, three modules including TypeScript in React, a typed project, and a free completion certificate.
• For type-system intuition, Total TypeScript's Beginner's TypeScript is the sharpest free tutorial, and the official Handbook is the canonical free reference.
• Exercism's TypeScript track is the best free practice tool once you know the basics.
• Watch for the certificate catch: Codecademy's lessons are free but its certificate is Pro-only, and freeCodeCamp's video course has no certificate.
• TypeScript is now a default skill: 40% of developers write exclusively in TypeScript, up from 34% in 2024.
• The natural free progression is JavaScript, then TypeScript, then React, before moving to a structured path like Scrimba's Frontend Developer Path.
