// =================== Square Area =================== //
// Create a function called computeArea that takes two arguments: width and height.
// It returns the area of a square whose width is width and height is height.
// So computeArea(2, 2) would return 4, and computeArea(3, 5) would return 15.

Q: Why are global variables avoided?
A: Because their values can be overwritten by the values of local variables.
   Local scope (function scope) can have access to global scope.
   Sometimes this can be useful like when we want global access to a library
   like JQuery in all our files. Or we want a function to have access in a database.

Q: Explain JavaScript's strict mode
A: When 'strict mode' is enabled declaring a variable without the var keyword, will rise an error.
  The 'use strict' command can be put at the top of a file to enforce strict mode for the entire file.

/* ======= max and min (without sort) ======= */

/*
To complete this drill, you need to implement two functions, max and min.
Both functions should take a single argument: a list of numbers called numbers.
max(myNumbers) should return the largest number in the list, while min(myNumbers)
should return the smallest.

Assume that the numbers input only contains numbers (that is, you don't have to
inspect your inputs to confirm they only contain numbers).

// ========= Most frequent word ========= //
/* In this drill, you need to implement a function named mostFrequentWord.
This function takes a single argument, words. Words is an array of lowercase strings,
with punctuation stripped out.
*/

function mostFrequentWord(words) {
    // `words` is an array of strings.
    // Create an empty object to hold most frequent words.
    var wordsObj = {};
