Affectation après division (/=)
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since juillet 2015.
L'opérateur de division et d'affectation (/=) divise la variable fournie par l'opérande gauche par la valeur indiquée par l'opérande droit puis affecte le résultat à la variable représentée par l'opérande gauche.
Exemple interactif
let a = 3;
a /= 2;
console.log(a);
// Expected output: 1.5
a /= 0;
console.log(a);
// Expected output: Infinity
a /= "hello";
console.log(a);
// Expected output: NaN
Syntaxe
js
Opérateur: x /= y;
Signification: x = x / y;
Exemples
