Interactive exampleOpen the canonical MDN source to run this embedded demo.
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
Syntax
x /= y
Description
x /= y is equivalent to x = x / y, except that the expression x is only evaluated once.
Examples
Division assignment using numbers
let bar = 5;
bar /= 2; // 2.5
bar /= 2; // 1.25
bar /= 0; // Infinity
Other non-BigInt values are coerced to numbers:
let bar = 5;
bar /= "2"; // 2.5
bar /= "foo"; // NaN
Division assignment using BigInts
let foo = 3n;
foo /= 2n; // 1n
foo /= 2n; // 0n
foo /= 0n; // RangeError: BigInt division by zero
foo /= 1; // TypeError: Cannot mix BigInt and other types, use explicit conversions
