How to calculate the WPMs ?

Calculating WPM:

WPM = ((Total Key Presses / 5) / Time in minute)

function CalculateWPM(keywords: number, time: number): number {
    return Math.round(((keywords / 5) / time));
}

Caulculating Accuracy:

Acc = (False Key Presses / Total Key Presses) * 100

function CalculateAcc(WKeystrokes: number, TKeystrokes: number): number {
    return Math.round((WKeystrokes / TKeystrokes) * 100);
}

Calculating Accuracy + WPM:

AWPM = WPM * (ACC / 100)

function CalculateAWPM(WPM: number, Acc: number): number {
    return Math.ceil(WPM * Acc);
}

What lagnuages can I train ?

You can train currently on 5 languages, but you can feel free to add you own language if you want :)

const wordArrays: WordArrays = {
    FR: mots,
    DE: worter,
    ES: palabras,
    KR: 단어,
    EN: words
}

these words are in the file words.ts, where the 5 languages are exported

How are the words added ?

Using some simple algorithm:

1. Take the list
2. take the word you typed (the first one of the list) and remove it
3. slide every word to -1
4. add a new word at the end of the list

function to make the algorithm (1, 2, 3):

function wordLineGen(newWord: string): string[] {
    wordlist.push(newWord);

    for (let i: number = 0; i < wordlist.length; i++)
        wordlist[i] = wordlist[i + 1];

    wordlist.pop();

    return wordlist;
}

to get a random word in the language you want (4):

function getRandomWord(): string {
    const selectedArray: string[] = wordArrays[lang] || words;
    const randomIndex: number = Math.floor(Math.random() * selectedArray.length);
    return selectedArray[randomIndex];
}
