# Get average age
|
|
|
|
Write the function `getAverageAge(users)` that gets an array of objects with property `age` and gets the average.
|
|
|
|
The formula for the average is `(age1 + age2 + ... + ageN) / N`.
|
|
|
|
For instance:
|
|
|
|
```js no-beautify
|
|
let john = { name: "John", age: 25 }
|
|
let pete = { name: "Pete", age: 30 }
|
|
let mary = { name: "Mary", age: 29 }
|
|
|
|
let arr = [ john, pete, mary ];
|
|
|
|
alert( getAverageAge(arr) ); // (25+30+29)/3 = 28
|
|
```
