Affectation aprs OU exclusif binaire (^=)

Baseline Large disponibilit

Cette fonctionnalit est bien tablie et fonctionne sur de nombreux appareils et versions de navigateurs. Elle est disponible sur tous les navigateurs depuis juillet 2015.

L'oprateur d'affectation aprs OU exclusif (XOR) binaire (^=) utilise la reprsentation binaire des deux oprandes, effectue un OU exclusif entre chaque puis affecte le rsultat obtenu la variable reprsente par l'oprande gauche.

Exemple interactif

let a = 5; // 00000000000000000000000000000101
a ^= 3; // 00000000000000000000000000000011

console.log(a); // 00000000000000000000000000000110
// Expected output: 6

Syntaxe

js
Oprateur: x ^= y;
Signification: x = x ^ y;

Exemples

Utiliser l'affectation aprs OU exclusif binaire

js
