createComparer

• createComparer<TSource, TSelect>(selector: Selector<TSource | TSource[], TSelect>, order?: Order | Order[], equivalentToNaN?: any): Comparison<TSource | TSource[]>

• A factory function that creates a comparer to be used in multi-dimensional sorting.

  Example

  var myArray = [{a:1:b:2},{a:3,b:4},{a:1,b:3}];
  
  // First sort by a, then by b.
  myArray.sort(
    createComparer(
      (e)=> [e.a, e.b],
      [Order.Ascending, Order.Descending]
    )
  );
  
  // result: [{a:1,b:3},{a:1:b:2},{a:3,b:4}]

  Parameters

  • selector: Selector<TSource | TSource[], TSelect>

  • Default value order: Order | Order[] = Order.Ascending

  • Default value equivalentToNaN: any = NaN

  Returns Comparison<TSource | TSource[]>
