I've found the vast majority of my issues with JavaScript is the modern tooling itself. I really like the new language improvements over the ES5 e.g. not having to worry about scope/hoisting issues, async/await, fetch is much simple to what came before.

The tooling on the other hand is often a Rube Goldberg machine transpilers, compilers etc. Some of the information is documented, some of it isn't and it can be a massive time sink to get everything working together and have your IDE / Editor correctly configured.

TypeScript can be nice, but I run into rough areas where you are actively fighting the type system.
