JavaScript-Zuweisungsoperatoren

Zuweisungsoperatoren weisen JavaScript-Variablen Werte zu.

Operator Beispiel Gleich wie
= 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
<<= 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
|= x |= y x = x | y
**= x **= y x = x ** y

Der Operator **= ist Teil von ECMAScript 2016.

Zuweisungsbeispiele

Der Zuweisungsoperator = weist einer Variablen einen Wert zu.

Abtretung

let x = 10;
Try it Yourself »

Der Zuweisungsoperator += fügt einer Variablen einen Wert hinzu.

Abtretung

let x = 10;
x += 5;
Try it Yourself »

Der Zuweisungsoperator -= subtrahiert einen Wert von einer Variablen.

Abtretung

let x = 10;
x -= 5;
Try it Yourself »

Der Zuweisungsoperator *= multipliziert eine Variable.

Abtretung

let x = 10;
x *= 5;
Try it Yourself »

Die Zuweisung /= teilt eine Variable.

Abtretung

let x = 10;
x /= 5;
Try it Yourself »

Der Zuweisungsoperator %= weist einer Variablen einen Rest zu.

Abtretung

let x = 10;
x %= 5;
Try it Yourself »

Testen Sie sich mit Übungen

Übung:

Verwenden Sie den richtigen Zuweisungsoperator, der dazu führt, dass x 15 ist (dasselbe wie x = x + y).

x = 10;
y = 5;
x  y;
