Chained functions may be context independent of their proceeding function, or they may be dependent on the results of the proceeding function. The Chaining Dependency Table below shows the relationship between immediately adjacent, chained functions.

Examples

  • gun.put({hello: "world"}).key("my/data")
    • key proceeded by put is dependent on the results of put
    • i.e. the key will be assigned to the same object as the put
  • gun.put({hello: "world"}).key("my/data").val(function(data){})
    • val proceeded by key is independent of the results of key, therefore val will work its way back to the previous dependent function, in this case the put function
    • i.e., both key and val are dependent on the results of put

Rows represent the initial function, while columns represent the subsequent function.

  • D : Subsequent function is dependent on the previous function.
  • i : Subsequent function is independent of the previous function.
