I didn't read JS The Good Parts until it was well outdated, and I was glad to see that a lot of the sharp edges that Crockford lists have largely been eliminated. The book was written circa ES3, so some problematic features were removed in strict mode, we have replacements for some (let/const, for-of loops, etc), and we can sweep prototypes under the rug with ES6 classes, sometimes arrow functions even avoid awkward this-binding issues. The rest, like you said, TypeScript + a linter takes care of.
