.JSFL File Extension

Script written in Flash JavaScript (JSFL), an API that extends regular JavaScript to include the Flash Document Object Model (DOM); contains JFSL program code written in a plain text format.

JSFL files are used to automate events and workflows in the Adobe Animate authoring environment. They can be created by selecting the following menu option: File → New → JSFL Script File.

NOTE: Animate was formerly known as Flash, which was originally developed by Macromedia but then merged with Adobe in 2005. Flash became Animate in 2016.
