Major Description
unique() algorithm is not correct in pivot.js file.
The algo is like this:
let unique = function (list) {
for (let i = 0; i < list.length; i++) {
for (let j = i + 1; j < list.length; j++) {
if (angular.equals(list[i], list[j])) {
list.splice(j, 1)
}
}
}
}
But it's not correct. If the input is [2, 3, 3, 3, 4, 5] and the output will be [2, 3, 3, 4, 5]. The number 3 is still duplicated.
