Multiplication ()
En esta página
The multiplication (*) operator produces the product of the operands.
{{InteractiveExample("JavaScript Demo: Multiplication (*) operator")}}
```js interactive-example console.log(3 * 4); // Expected output: 12
console.log(-3 * 4); // Expected output: -12
console.log("3" * 2); // Expected output: 6
console.log("foo" * 2); // Expected output: NaN
## Syntax
```js-nolint
x * y
Description#
The * operator is overloaded for two types of operands: number and BigInt. It first coerces both operands to numeric values and tests the types of them. It performs BigInt multiplication if both operands become BigInts; otherwise, it performs number multiplication. A {{jsxref("TypeError")}} is thrown if one operand becomes a BigInt but the other becomes a number.
Examples#
Multiplication using numbers#
2 * 2; // 4
-2 * 2; // -4
Infinity * 0; // NaN
Infinity * Infinity; // Infinity
Other non-BigInt values are coerced to numbers:
"foo" * 2; // NaN
"2" * 2; // 4
Multiplication using BigInts#
2n * 2n; // 4n
-2n * 2n; // -4n
You cannot mix BigInt and number operands in multiplication.
```js example-bad 2n * 2; // TypeError: Cannot mix BigInt and other types, use explicit conversions 2 * 2n; // TypeError: Cannot mix BigInt and other types, use explicit conversions
To do multiplication with a BigInt and a non-BigInt, convert either operand:
```js
2n * BigInt(2); // 4n
Number(2n) * 2; // 4
