Arrows, braces, backticks, and destructuring — JavaScript syntax lives on the keys prose never touches. Drill real statements until the symbols disappear.
Opens the test — choose Code mode; JavaScript is the default language.
What you'll type
The JavaScript bank contains twelve real single-line statements. Two examples, exactly as served:
const arr = [1, 2, 3].map(x => x * 2);
const { name, age } = person;
Arrow functions, array methods, destructuring, async/await fetch calls, try/catch blocks, event listeners, and a React-style component and useState hook — the lines JavaScript developers type all day.
What JavaScript typing trains
The arrow — => chains two shifted characters and appears in nearly every modern callback.
Brace pairs — object literals, destructuring, and blocks keep both `{}` under your right hand constantly.
Backticks — template literals use a corner key most typists have never deliberately practiced.
Semicolons and commas — terminators demand a rhythm prose punctuation doesn't build.
Scoring is first-strike — every character position counts once, on your first attempt — so a fumbled brace stays in your error count. Details on the typing accuracy test page.
Frequently Asked Questions
What kind of JavaScript will I type?
Twelve real single-line statements: arrow functions, array methods like map/filter/reduce, destructuring, async/await fetch calls, try/catch, event listeners, and a React-style component and hook. Each round serves one snippet, character-exact.
Why practice typing JavaScript specifically?
JavaScript stacks the keyboard's hardest characters: => arrows, curly and square brackets, backtick template literals, and semicolons. They're nearly absent from prose, so prose practice never builds them — dedicated drills do.
Does this cover TypeScript too?
TypeScript has its own snippet bank — interfaces, generics, unions, and enums — selectable from the same language dropdown in Code mode.
How do I start JavaScript typing practice?
Open the typing test, select Code mode, keep JavaScript selected in the language dropdown (it's the default), and press Start. Results are saved to your local history.
