From the JavaScript Tools Guide CC.pdf found via ESTK->Help menu item.

In all ExtendScript scripts, the #target directive can use an specifier to identify the application that

should run that script. See “Preprocessor directives” on page 233.

Preprocessor directives on page 233

JavaScript engine, and setting certain flags. Specify these with a C-style statement starting with the #

character:

#include "file.jsxinc"

....

Thus the name ExtendScript ....
