“Считать овец” Ответ

Считать овец

//Consider an array/list of sheep where some sheep may be missing from their place. We need a function that counts the number of sheep present in the array (true means present).

/* For example,
  [true,  true,  true,  false,
  true,  true,  true,  true ,
  true,  false, true,  false,
  true,  false, false, true ,
  true,  true,  true,  true ,
  false, false, true,  true]
*/
// The correct answer would be 17.

function countSheeps(arrayOfSheep) {
  let numberOfSheep = 0
  arrayOfSheep.forEach(sheep => sheep ? numberOfSheep++ : false)
  return numberOfSheep
}
