Create a function which returns the number of true values there are in an array.

Examples

countTrue({true, false, false, true, false}) ➞ 2

countTrue({false, false, false, false}) ➞ 0

countTrue({}) ➞ 0

Notes

  • Return 0 if given an empty array.
  • All array items are of the type bool (true or false).
