Counting_sheep.js

/* Task : 

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. */

const counting = (arr) => {
   var sum = 0
   
   for (let i = 0 ; i <arr.length ; i++){
    arr[i] === true ? sum = sum + 1 : null
   }

   return sum

}

console.log(counting([true,  true,  true,  false,
  true,  true,  true,  true ,
  true,  false, true,  false,
  true,  false, false, true ,
  true,  true,  true ,
  false, false, true,  true]))
