## Partial updates with `PATCH` { #partial-updates-with-patch }

You can also use the <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PATCH" class="external-link" target="_blank">HTTP `PATCH`</a> operation to *partially* update data.

This means that you can send only the data that you want to update, leaving the rest intact.

/// note

`PATCH` is less commonly used and known than `PUT`.

pkg log, method (*Logger) Writer() io.Writer
pkg math/bits, func Add(uint, uint, uint) (uint, uint)
pkg math/bits, func Add32(uint32, uint32, uint32) (uint32, uint32)
pkg math/bits, func Add64(uint64, uint64, uint64) (uint64, uint64)
pkg math/bits, func Div(uint, uint, uint) (uint, uint)
pkg math/bits, func Div32(uint32, uint32, uint32) (uint32, uint32)
pkg math/bits, func Div64(uint64, uint64, uint64) (uint64, uint64)

    K unmappedKey;
    try {
      map = makePopulatedMap();
      unmappedKey = getKeyNotInPopulatedMap();
    } catch (UnsupportedOperationException e) {
      return;
    }
    assertFalse(map.containsKey(unmappedKey));
    try {
      assertFalse(map.containsKey(new IncompatibleKeyType()));
    } catch (ClassCastException tolerated) {
    }
    assertTrue(map.containsKey(map.keySet().iterator().next()));

И данные будут сохранены с этим "новым" `tax`, равным `10,5`.

## Частичное обновление с помощью `PATCH` { #partial-updates-with-patch }

Также можно использовать <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PATCH" class="external-link" target="_blank">HTTP `PATCH`</a> операцию для *частичного* обновления данных.
