The * operator produces the product of the operands.
The * operator produces the product of the operands.
x * y
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 TypeError is thrown if one operand becomes a BigInt but the other becomes a number.
2 * 2; // 4 -2 * 2; // -4
Infinity * 0; // NaN Infinity * Infinity; // Infinity
"foo" * 2; // NaN "2" * 2; // 4
2n * 2n; // 4n -2n * 2n; // -4n 2n * 2; // TypeError: Cannot mix BigInt and other types, use explicit conversions // To multiply a BigInt with a non-BigInt, convert either operand 2n * BigInt(2); // 4n Number(2n) * 2; // 4
