Strongly recommend you get used to it. JavaScript is the universal language of the future. What can be written in JS will be written in JS. This is just a fact my man. Not because it&#x27;s superior to other languages, it&#x27;s simply because it is more cost effective to use. For example, at my current company, we are now using a Node Microservices architecture, Cassandra, Redis, Relay, GraphQL, and React. We&#x27;re doing all our mobile using React Native. We were a Rails Angular shop before. All our engineers are now full-stack JS. We were able to get rid of 75% of our engineers using this stack...and then hire much higher quality engineers...JS experts. I can&#x27;t tell you what a pleasure it is to work with this stack vs. something like Rails + Angular. And as for performance, it moves like nothing I&#x27;ve ever seen before. Warp speed brother. JS is the future my man. It&#x27;s the only programming language I would invest my time in learning...i mean if you&#x27;re concerned about job security and all. If not, I would spend my time learning Elixir and Phoenix. Also TensorFlow.
