Map() reference error

See original GitHub issue

duktape supports the Javascript Map type, right? Why do I get a reference error when I use it:

Error encountered: sync/test-sync.js
ReferenceError: identifier 'Map' undefined
    at processTestCase (sync/test-sync.js:158)
    at processModule (sync/test-sync.js:136)
    at syncTestModules (sync/test-sync.js:109)
    at runSynchronization (sync/test-sync.js:88)
    at global (sync/test-sync.js:63)
    at [anon] (eval:1)
The terminal process terminated with exit code: 2

For the code line:

var t = new Map();

I recently upgraded to version 2.2.1.

Update

The same happens with Set, while Array works as expected.

@mike-lischke I was able to work around this by using the ‘es6-shim’ package: import { Map } from 'es6-shim'; prior to the import that called the Map constructor.

Yes, sure, but it hasn’t even come to my mind that such standard types wouldn’t be available. I use them constantly in other projects and feel quite limited without them 😃
