TypeScript Typing Test

Practice typing real TypeScript code — the symbols, keywords and indentation you use every day. Measures coding WPM, accuracy and syntax accuracy.

Enter = new line · Tab = indent · Esc = restart. A wrong key is counted and the cursor waits for the right one.

Tips for typing TypeScript

TypeScript adds type annotations on top of JavaScript: colons after names, angle brackets for generics and | for unions. Watch the Shift-heavy <T> and ?: pairs — they cost more than they look.

A TypeScript snippet you might get

class Stack<T> {
  private items: T[] = [];
  push(item: T): void {
    this.items.push(item);
  }
  pop(): T | undefined {
    return this.items.pop();
  }
}

Code typing tests by language

How the code typing test works

  1. Pick a language and length, click the editor and start typing — the timer starts on your first key.
  2. 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.
  3. 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.
  4. 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.
