Exercises 2.(No. 1820)

JavaScript(Emacs)

var words = ['scheme', 'c', 'javascript', 'scala', 'python'],
    i,
    max;

print(words);
print('forword--------------------------------------------------');
for (i = 0, max = words.length; i < max; i += 1) {
    print(words[i]);
}
print('backword--------------------------------------------------');
for (i = words.length - 1; i >= 0; i -= 1) {
    print(words[i]);
}
