Coding typing practice

Type real code. Brackets, quotes, operators and line breaks are where developers lose the most time, so this practice puts them front and centre.

Debounce function · JavaScript

Press Enter at the end of each line. Indentation is filled in for you.

function debounce(fn, wait = 300) {↵ let timer;↵ return (...args) => {↵ clearTimeout(timer);↵ timer = setTimeout(() => fn(...args), wait);↵ };↵}

Typing practice for programmers

Code uses far more symbols than prose: braces, parentheses, arrows, quotes and semicolons. Practising them on purpose makes everyday coding smoother and reduces typos that cause bugs.

Real snippets

Short, realistic examples in JavaScript, TypeScript, Python, HTML, CSS, SQL and Go, the kind of code you write every day.

Enter and auto-indent

Press Enter at the end of each line, like in your editor. Leading spaces are filled in automatically so you can focus on the code itself.

Symbols first

Watch the missed-keys list after each snippet. Most coders find brackets and the shift-row symbols are their slowest keys.

Combine with drills

Use smart practice for letters and this page for symbols. Together they cover everything you type at work.
