Need to provide sort direction details on sortComparer method api

Within the "SortComparer" function, it is already possible to receive parameters x and y.

sortComparer: (x: ValueType, y: ValueType) => {
  // Using the x and y parameters.
},



If the "sortAsc" variable could also be accepted as a parameter, I believe there is no need to create the "sortAsc" local variable.

sortComparer: (x: ValueType, y: ValueType, sortAsc: boolean) => {
if (sortAsc && x === null) {
  return -1
} else if (sortAsc && y === null) {
  return 1
} else if (!sortAsc && x === null) {
  return -1
} else if (!sortAsc && y === null) {
  return 1
} else {
  return x - y
}
},


I would appreciate your consideration of my idea.
