Export command

[ramblerswebs]

I am a newbie to JS so this is probably a stupid question, but any help would be greatly appreciated
I am using version 1.3.8
I have copied the zip across to my PC and in my html I have a link to the FileSave.js file (from src folder)
When I view this file in Netbeans it gives an error on the export in line 16 and the return line a few statements down.
If I run the code Firefox 60.0.1 gives the error
SyntaxError: export declarations may only appear at top level of a module FileSaver.js:16:1

So I tried deleting the export (as I noticed this is not in the minified file used in the demos)
This removes the error two msgs. But I now have to access FileSaver.saveAs(blob, "hello world.txt");
with saveAs(blob, "hello world.txt");

This now seems to work but some browsers now tell me the download did not complete.

Any help gratefully received.

FileSaver.js uses exports syntax that not all browsers support. As a workaround, either use an old version of FileSaver.js, or set up your build system to use a tool like Babel to convert FileSaver.js to an older ECMAScript version.
