Extremely interested & dedicated to learning to code. But where to start?? Thinking machine learning, AI, or cyber security

Python I think is currently leading on AI platform, but Javascript (Tensorflow.js) will be possible too, but it might be a bit harder here

Roel, thank you. Where would be a good place to learn JavaScript?

https://www.w3schools.com https://sololearn.com and the Tensorflow.js site (don't know link)
