Code Typing Practice
Type the function shown on the left. Timer counts up from zero — no pressure. Finish when you're done and see your WPM and accuracy.
How this works
Type the function
The reference code is on the left. Type it in the box on the right. Characters on the left highlight blue when correct and red when wrong.
No time pressure
The timer counts up from zero. There is no countdown. Finish the function at whatever pace you choose.
No shortcuts
Paste is blocked. Cursor cannot be repositioned with the mouse. Every character must be typed manually.
Full result
When you finish typing the last character your result page shows WPM, accuracy, errors, and a shareable certificate.
Why Practice Typing Code?
Code contains a far higher density of special characters than ordinary prose — brackets, semicolons, underscores, comparison operators, and quotation marks appear constantly. A developer who types prose at 70 WPM may drop significantly when typing code because those characters demand finger movements that are rarely practiced. Code typing practice directly targets this gap by training your hands on the exact patterns you encounter while programming.
Accuracy matters more in code than in prose. A single misplaced bracket causes a syntax error. Building the muscle memory to type symbols accurately at speed reduces cognitive load and lets you focus on the problem you are actually solving rather than the mechanics of getting it onto the screen.
What Languages Are Included?
This tool includes functions in JavaScript, Python, Java, C, C++, Go, SQL, and TypeScript. Each language has its own typing character profile. Python uses significant indentation and colons. Java requires more semicolons and type declarations. Go uses short variable declaration syntax. C++ introduces template syntax and standard library prefixes. SQL uses keyword-heavy uppercase patterns. TypeScript adds type annotation syntax on top of JavaScript.
How WPM Is Calculated
The standard five-character word formula is used — total correct characters divided by five gives a word count, divided by elapsed minutes gives gross WPM. Net WPM deducts errors using the standard formula. This matches the formula used by the other typing tests on this site so your score is directly comparable.
Frequently asked questions
This is a practice tool, not a timed exam. The timer counts up from zero so you can see how long you took, but there is no pressure to finish within a set window.
Paste is blocked so the test measures genuine typing speed. Every character must be typed manually.
