⤴️return
🚧 施工中
JS ⟩ statement ⟩ control flow ⟩ jump ⟩ return
return statement can be used only within the body of a function, using it anywhere else causes a SyntaxError.
return is affected by automatic semicolon insertion❗
⚠️ 注意:用 return
時,不要寫成這樣:
return
a + b;
❌ 這種寫法 return
後面會被自動加上 ";
" 分號❗
return; // 自動加上「;」分號❗️
a + b;
✅ 建議寫成這樣:
return (
a + b
);
