賦值運算子

JavaScript 教學 中提到的賦值運算子，將賦值運算符視為「=」。第一次接觸程式碼的人可能會以為它是「等於」，但其實不是。它實際上意味著把右邊表達式的值賦給左邊的運算數。

JavaScript 賦值運算子 敘述 範例 ＝ x = y x = y +＝ x += y x = x + y -＝ x -＝ y x = x - y *＝ x *＝ y x = x * y /＝ x /= y x = x / y %＝ x %= y x = x % y

你可以在 JavaScript 中的同一行中，使用多種運算子，如在下面例子所示：

你也可以運用多種變數，例子如下：

JavaScript賦值運算子	敘述	範例
＝	x = y	x = y
+＝	x += y	x = x + y
-＝	x -＝ y	x = x - y
*＝	x *＝ y	x = x * y
/＝	x /= y	x = x / y
%＝	x %= y	x = x % y
