Conversion of integers to English words Using Javascript.

function amountToWords(numericAmount) {
    const ones = ['Zero', 'One', 'Two', 'Three', 'Four', 'Five', 'Six', 'Seven', 'Eight', 'Nine'];
    const teens = ['Eleven', 'Twelve', 'Thirteen', 'Fourteen', 'Fifteen', 'Sixteen', 'Seventeen', 'Eighteen', 'Nineteen'];
    const tens = ['', 'Ten', 'Twenty', 'Thirty', 'Forty', 'Fifty', 'Sixty', 'Seventy', 'Eighty', 'Ninety'];

    let words = '';

    if (numericAmount === 0) {
        return 'Zero';
    }

    if (numericAmount < 0) {
        words += 'Negative ';
        numericAmount = Math.abs(numericAmount);
    }

    if (numericAmount >= 1000000) {
        words += amountToWords(Math.floor(numericAmount / 1000000)) + ' Million ';
        numericAmount %= 1000000;
    }

    if (numericAmount >= 1000) {
        words += amountToWords(Math.floor(numericAmount / 1000)) + ' Thousand ';
        numericAmount %= 1000;
    }

    if (numericAmount >= 100) {
        words += amountToWords(Math.floor(numericAmount / 100)) + ' Hundred ';
        numericAmount %= 100;
    }

    if (numericAmount >= 20) {
        words += tens[Math.floor(numericAmount / 10)] + ' ';
        numericAmount %= 10;
    }

    if (numericAmount >= 11 && numericAmount <= 19) {
        words += teens[numericAmount - 11] + ' ';
    } else if (numericAmount > 0) {
        words += ones[numericAmount] + ' ';
    }

    return words.trim();
}

let enWords = amountToWords(122)
console.log (enWords)
// RESULT: One Hundred Twenty Two
