- The simplest way to complete this challenge is to create an `ìf-statement` to check wether or not the object contains all users, then to return a true or false statement. The first solution does just this.
- The second solution works in exactly the same way, only it uses 1 line of code - `Conditional(ternary)-Operator` - within the function.
