You don't return all of the quotes

You use number 324 in index,js but you have 326 quotes. That means, the last 2 quotes will never return. Please don’t use magic numbers in code. It’s a well known anti-pattern. Just replace the value with arr.length.

While you are at it, you can simplify your functions with:

module.exports.getQuote = function (name) { 
    return arr[randomInt(arr.length)]    //rename your from field to author in data.json
};

That is faster, because you do one less array access, and simpler because of the error I mentioned above.

@jabbar86 I have already taken it, but we can match a fight on the streets to see who survives and who can take this issue
