Problems

Test all your solutions for the questions 1-4 with the following variable:

const alumni = [
{name:'Jarrit', job:'TPT',language:'JavaScript', age:23}, 
{name:'Stephanie', job:'JPMorgan',language:'JavaScript', age:24}, 
{name:'Devonte', job:'WW',language:'JavaScript', age:23},

{name:'Jan', job:'Square Space',language:'JavaScript', age:22},
{name:'Uzma', job:'Thyme Care',language:'JavaScript', age:22}]

1. Write a function named averageAge that takes an array of objects and returns the average of all the ages from each age property in each object rounded to the nearest whole number.

   averageAge(alumni) // 22

2. Write a function named orderedAlumni that takes an array of objects and sorts the objects by the age of the alumni from oldest to youngest.

   orderedAlumni(alumni) // returns [
     { name: 'Devonte', job: 'WW', language: 'JavaScript', age: 23 },
     {
       name: 'Shemar',
       job: 'SquareSpace',
       language: 'JavaScript',
       age: 23
     },
     { name: 'Jarrit', job: 'TPT', language: 'JavaScript', age: 22 },
     {
       name: 'Stephanie',
       job: 'JPMorgan',
       language: 'JavaScript',
       age: 21
     },
     { name: 'Enmanuel', job: 'Asana', language: 'JavaScript', age: 21 },
     { name: 'Cielo', job: 'NYT', language: 'JavaScript', age: 21 }
   ]

3. Write a function named allUseJavaScript that takes an array of objects and returns a boolean if for every object, the language property is 'JavaScript'.

    ```jsx
    allUseJavaScript(alumni) // returns true
    ```
