Ⓜ️.valueOf()

🚧 under construction

JS ⟩ value ⟩ type ⟩ conversion ⟩ .valueOf()

convert object to (primitive) value, if possible.

⭐️ 重點

• in order for valueOf to be useful during type conversion, it must return a primitive.

• all primitive types have their own custom valueOf methods.

⚖️ valueOf vs. toString

• valueOf is called in priority by numeric conversion and primitive conversion.

• string conversion calls toString() in priority.
