What is Sajax?

Sequential Ajax, or Sajax, is an Ajax design pattern for making simultaneous asynchronous HTTP requests and handling their respective callbacks sequentially, regardless of the order in which they return, with each callback function receiving the return value of the previous callback function as an additional argument.

By sharing data between callbacks, Sajax facilitates the combination and manipulation of data from multiple requests without complicated workarounds to handle the inherent timing issues of Ajax's asynchronous nature.

Simultaneous Request/Sequential Response

Using wrapped functions and custom events, Sajax ensures proper ordering of callbacks.
