# JavaScript scripting API (WIP)
## Note: This documentation is still work in progress! 
Todo:
- Add missing parameters
- Add missing returns
- Add examples

## Description
Momentum supports JavaScript scripting using [mjs](https://github.com/cesanta/mjs). 
**Note: Read about mjs's limitations in the link above! You will experience alot of missing js features (e.g. createTimeout).**
