Typing Game

A minimal browser typing test built with React and Vite. You type a shuffled passage against a fixed timer; when time runs out, you see WPM (words per minute) and accuracy based on how you performed.

Features

• 30-second timed run — countdown shown at the top of the game area.
• 50 random words per round, drawn from a built-in word list and shuffled each start.
• Live feedback — each letter is colored as you type (correct / incorrect); the active word is highlighted; words with at least one mistake get a red underline when you move on.
• Space advances to the next word (current word is scored as fully correct or “marked” if any letter was wrong).
• Backspace edits the current word; with an empty input at the start of a word, backspace returns to the previous word so you can fix mistakes.
• Hidden input + global key focus — almost any key refocuses the typing field so play feels smooth.
• Results screen — WPM and accuracy after the timer hits zero; reload starts a new round with a fresh shuffle.

Prerequisites

• Node.js 18+ (recommended; Vite 5 expects a current Node version)
• npm (or use pnpm / yarn if you prefer — adjust commands accordingly)

How to Play

1. Focus — Click the page or press a key so the hidden input is focused (the game tries to focus it on keydown).
2. Type the highlighted word letter by letter. Green = correct, red = wrong character for that position.
3. Press Space to submit the current word and move to the next.
   • If every typed letter in that word matched the target, the word counts as correct for WPM.
   • If any letter was wrong or missing, the word is marked (visual underline); it does not count toward the “correct words” WPM tally.
4. Use Backspace to correct within the word. At the beginning of a word with empty input, backspace jumps back to the previous word and restores what you had typed there (wrong letters appear as * in the input while you edit).
5. When the timer reaches 0, the game hides the passage and shows WPM and Accuracy. Use the reload button to play again.

Note: On the last word of the passage, Space does not advance (there is no next word); the timer keeps running until it finishes.

Scoring (How Results Are Calculated)

WPM (words per minute)

Only words that were submitted with all letters correct count:

WPM = (number of correct words) ÷ (test duration in minutes)

The test duration is 30 seconds (0.5 minutes), so effectively:

WPM = correct words × 2

(The implementation uses correctWords / (initialTime / 60) and displays one decimal place.)

Accuracy

Accuracy uses every letter that was ever classified as correct or incorrect in the paragraph (typically letters you actually typed in the current or past words):

Accuracy = (correct letters) ÷ (correct letters + incorrect letters) × 100%

If you have not typed anything that produced letter states, accuracy shows 0%.
