Abstract: Various aspects of the subject technology relate to executing a task in a single-threaded environment. A first set of subtasks for the task may be generated and scheduled for execution in a runtime environment with a single logical thread based on a first function. The first set of subtasks may be executed based on the scheduling of the first set of subtasks, wherein the execution of the first set of subtasks generates a set of key/value pairs. A second set of subtasks may also be generated and scheduled based on the execution of a second function on the set of key/value pairs. The second set of subtasks may be executed based on the scheduling of the second set of subtasks.

Abstract: A system and method for dynamically modifying web forms in a hosted form application execution environment is disclosed. A web form can be generated for displaying and collecting information from an end user. A trigger can be created that executes on a specific trigger event. When the specified trigger event occurs, a script may be automatically executed to dynamically alter the web form. Then, the altered web form can be displayed to the end user.
