JavaScript Typing Test
Practice typing real JavaScript code — the symbols, keywords and indentation you use every day. Measures coding WPM, accuracy and syntax accuracy.
Click here and start typing
Enter = new line · Tab = indent · Esc = restart. A wrong key is counted and the cursor waits for the right one.
Your coding speed
Syntax accuracy only counts brackets, quotes, operators and punctuation — the characters that cause syntax errors.
Characters you missed
No misses — flawless!
Tips for typing JavaScript
JavaScript is heavy on braces, parentheses and arrow functions. The slowest keys are usually {, }, => and the backtick for template literals — practise ${…} until it flows, and keep your right pinky close to the bracket keys.
A JavaScript snippet you might get
function debounce(fn, delay) {
let timer = null;
return (...args) => {
clearTimeout(timer);
timer = setTimeout(() => fn(...args), delay);
};

How the code typing test works
- Pick a language and length, click the editor and start typing — the timer starts on your first key.
- Press Enter for new lines. With auto-indent on, leading spaces are skipped just like in your editor; turn it off to practise indentation too.
- A wrong key flashes red and is counted, but the cursor waits for the correct character — so every slip is measured without leaving broken code behind.
- Your result shows coding WPM, overall accuracy, syntax accuracy and the exact characters you missed most.
Code typing test — FAQ
What is a good typing speed for programmers?
Coding WPM is usually 30–50% lower than prose WPM because of symbols, casing and indentation. 40–60 code WPM with 95%+ accuracy is solid; above 70 is excellent.
What is syntax accuracy?
It's your accuracy on non-letter characters only — brackets, braces, quotes, semicolons and operators. These are the keys behind most syntax errors, so it's the number worth improving.
Which languages can I practise?
JavaScript, TypeScript, Python, SQL, Java, C#, C++, Go, Rust, PHP, HTML, CSS and Bash — all real-world snippets.
Does faster typing make you a better programmer?
Thinking matters more than typing, but fluent symbol typing removes friction: fewer typos, fewer broken builds, and more attention left for the actual problem.
