Fact · Typing and writing speed
Monkeytype's missed-word practice sorts the words you missed by how often you missed them, and keeps only the top of that list.
Checked against its source on October 17, 2026
In the source's own words
“sortableMissedWords.sort((a, b) => { return b[1] - a[1]; }); sortableMissedWords = sortableMissedWords.slice(0, limit);”
Monkeytype source code: frontend/src/ts/test/practise-words.ts (missed-word practice), GitHub (monkeytypegame/monkeytype), main branch, n.d., init function, missed words branch.
Open the original- What it measures
- The code counts misses for each word from the last test, sorts the list from most to fewest, and cuts it to a set limit before it builds the practice test.
- What it does not show
- The source shows how the list is built, not whether practising it improves speed. The limit depends on the mode, so check the practice option on the site.
