sort

Sorts and returns elements contained in a list, a set of unique values or a sorted set. By default, sorting is numeric and elements are compared by their value interpreted as double precision floating point number.

While Kuzzle's API supports the "store" option for this command, Kuzzle SDK methods do not. To sort and store in the same process, use the [query method](/sdk/js/5/core-classes/kuzzle/query)

// Using promises (NodeJS only)
kuzzle.memoryStorage.sortPromise('key')
  .then(values => {
    // resolved once the action has completed
  });
