JS ⟩ value ⟩ type ⟩ conversion ⟩ falsy

7 falsy values：(converts to false)

• false, 0, 0n, null, undefined, NaN, "" (empty string).

any other value is "truthy", and converts to true.

⭐️ 重點

every value is either truthy or falsy❗

all objects are truthy (convert to true).

operator(s) that expect boolean operands will work with an operand of any type❗
