示例1: partition2

 partition2() {
   const source = from([1, 2, 3, 4, 5, 6]);
   // if greater than 3 throw
   const example = source.pipe<{success: number, error: number},{success: number, error: number}>(
     map(val => {
       if (val > 3) {
         // throw `${val} greater than 3!`;
       }
       return { success: val, error: null };
     }),
     catchError(val => of({ success: null, error: val }))
   );
   // split on success or error
   const [success, error] = partition<{success: number, error: number}>(res => res.success !== null)(example);
   /*
     Output:
     "Success! 1"
     "Success! 2"
     "Success! 3"
     "Error! 4 greater than 3!"
   */

     success.pipe(map(val => `Success! ${val.success}`)),
     error.pipe(map(val => `Error! ${val.error}`))
