Some coding challenges for the AO front end team who are learning JavaScript

Write a function that takes a name and decides how lucky that person is

/*

    The function should convert the name into a number (somehow?) and multiply it by the current time.
    The answer should be divided by 2. If that number is even, the person is cool, otherwise they're not :(

*/

function arrayOfStringsToNum(arr) {
    var alphabet = strToArray("abcdefghijklmnopqrstuvwxyz");
    return arr.reduce((a, b) => a += alphabet.indexOf(b.toLowerCase()), 0);
}

function strToArray(str) {
    return str.split("").filter(letter => !~letter.indexOf(" "));
}

function getTime() {
    return new Date().getTime();
}

function divide(by) {
    return function(num) {
        return Math.floor(num / by);
    }
}

function isEven(num) {
    return num % 2 === 0;
}

function isCool(str) {
    return isEven(divide(2)(arrayOfStringsToNum(strToArray(str)) * getTime()));
}

var mike = "Michael Chadwick";
console.log(isCool(mike));
