🔰error handling

JS ⟩ async ⟩ Promise ⟩ error handling

⭐️ 重點

• .catch() callback is for：

  • reporting errors

  • handling errors

  • recovering from errors

• .catch() callback can throw a new error, but if it returns normally, than that return value is used to resolve (fulfill) the associated Promise, and the error stops propagating.
