The next version of JS++ will feature the ‘class’ keyword and is expected for Q1 2017.
In addition, Mac and Linux users will benefit from a JS++ installer:
The installer is completely optional. However, it will be useful if you don’t want to manually install JS++ and various editor plugins. We auto-detect which editors are installed on your system, and, if a plugin is available, we will attempt to install it for you.
