Python or Javascript. Which one to choose for a basic proj?

I have attended the "AI Crash Course – Adding ML to Your Software Projects in an Hour" and the presenter was using JS/Node for the demo. Although I know there is lots of fuzz around Python when talking about AI, ML, Data Science and BI.

Which one do you recommend? Which one is more mature, has more community involved and more examples/tutorials to start my ML path?

I am equally comfortable both with Python and JS.
