// sumUnique([1, 2, 2, 3, 4, 4, 5]) ==> 1 + 3 + 5 => 9
// sumUnique([10, 20, 20, 30, 40, 40, 50]) ==> 10 + 30 + 50 => 90
// sumUniquey([5, 5, 10, 15, 20, 25, 25]) => 10 + 15 + 20 => 45
const sumUnique = (arr)=>{
return Object.entries(arr.reduce(function (obj, value2 ){
return (obj[value2] ? ++obj[value2] :(obj[value2] = 1),obj)
},{})).filter(([key,value]) => value === 1).flat().filter(el => typeof el == 'string').reduce((a,b) => parseInt(a)+ parseInt(b) ,0)
