There are a lot of negatives, but it is any easy language to make rapid progress writing code in, and ES6 or TypeScript have made it a lot better than it used to be. You can do a lot of prototyping in the browser REPL too (e.g. I like to go to the lodash docs, write out code on the site, then paste into my app).
It's nice to be able to do server side rendering (i.e. run React there). Also you can run all the build tools in your application server during development which can be super convenient - Probably the most compelling example I've seen of this is Next.js.
