Thanks admin for sharing. Decompiles small files well, But jsxbin files over 100kb cannot be decompiled, the translated file is reversed with functions and variables

File ActionToJavascript.jsx is is the original file
File 1.jsxbin has been encoded into jsxbin
File 1.jsx has been decoded with jsx from jsxer
File 1.jsx : The functions in the jsxer decoded file are turned upside down and not intact like the original file

The statements appear out of order but not quite in reverse order. Thanks for letting me know about this.

I don't think it is a big. It's how the js is compiled and read after. it's part of the EcmaScript(js) engine's parsing and execution flow.

Global objects like functions doesn't need to be in order to reference it in pre or post line. Unlike C, EcmaScript(js) doesn't need a forward declaration. the EcmaScript engine doesn't keep track of the function object's order when parsing from the source.
