// Work through the problems in this file.  As you work through each problem periodically run: npm test
// Your function name and the string must match the instructions exactly otherwise the tests will fail.
// After writing your function uncomment the matching function reference at the bottom of the file.


// 1. Write a function called helloWorld that returns the string 'Hello World!'.

// 2. Write a function called lambdaSchool that has a single parameter called num.
//      num will be a positive integer.
//      If num is divisible by 3 return the string 'Lambda'
//      If num is divisible by 5 return the string 'School'
//      If num is divisible by 3 AND 5 return the string 'Lambda School' (notice the space)
//      If num is NOT divisible by 3 or 5 then return num.
//      
//      Example: 
//              lambdaSchool(15); // returns 'Lambda School'
//              lambdaSchool(8); // returns 8

// 3. Write a function called longestString that has a single parameter called strs.
//      strs will be an array of strings.
//      Return the longest string that is in strs.
//      If there is a tie for the longest string then return the one that occurs first.
//
//      Example:
//              longestString(['hi', 'hello', 'ni hao', 'guten tag']); // returns 'guten tag'
//              longestString(['JavaScript', 'HTML', 'CSS']); // returns 'JavaScript'

// 4. Write a function called computeUserAverageAge that has a single parameter called users
//      users is an array of user objects.
//      Each user object has a property called age that is a number.
//      Compute the average age of all user objects in the users array.
//      Round off the decimals if needed and return the number.
//
//      Example:
//              const users = [{
//                name: 'Brendan Eich',
//                age: 56,
//              }, {
//                name: 'Linus Torvalds',
//                age: 48,
//              }, {
//                name: 'Margaret Hamilton',
//                age: 81,
//              }];
//              computeUserAverage(users); // returns 62 (This number is rounded up from 61.6666)


module.exports = {
//  helloWorld,
//  lambdaSchool,
//  longestString,
//  computeUserAverageAge,
