Core syntax and types: variables, types, operators, control flow, functions, and arrays. Be able to write simple programs fluently. Everything else builds on this, so do not skip it even if it feels basic.
After core syntax, scope, and functions. Async is a huge part of modern JS and is tested heavily, but it builds on understanding functions and closures first. Do async after you have the foundation.
Because interviews require coding by hand and explaining out loud, not just reading. Practice problems on closures, async, event loop ordering, and prototypes train the actual skills interviews test, which study alone does not.
