A version with a compact object - for numbers from zero to 999.

function wordify(n) {
    var word = [],
        numbers = { 1: 'One', 2: 'Two', 3: 'Three', 4: 'Four', 5: 'Five', 6: 'Six', 7: 'Seven', 8: 'Eight', 9: 'Nine', 10: 'Ten', 11: 'Eleven', 12: 'Twelve', t3: 'Thir', t5: 'Fif', t8: 'Eigh', 20: 'Twenty' },
        hundreds = 0 | (n % 1000) / 100,
        tens = 0 | (n % 100) / 10,
        ones = n % 10,
        part;

    if (n === 0) return 'Zero';
    if (hundreds) word.push(numbers[hundreds] + ' Hundred');

    if (tens === 0) {
        word.push(numbers[ones]);
    } else if (tens === 1) {
        word.push(numbers['1' + ones] || (numbers['t' + ones] || numbers[ones]) + 'teen');
    } else {
        part = numbers[tens + '0'] || (numbers['t' + tens] || numbers[tens]) + 'ty';
        word.push(numbers[ones] ? part + '-' + numbers[ones] : part);
    }
    return word.join(' ');
}

var i,
    output = document.getElementById('out');

for (i = 0; i < 1e3; i++) output.innerHTML += wordify(i) + '\n';
