The value of x after the code executes will be null. The logical AND (&&) operator in JavaScript returns the first falsy operand it encounters, or the last operand if all are truthy. Since null is falsy, the expression null && 5 short-circuits at null and returns null. This behavior of && is used in patterns like obj && obj.property to avoid errors when obj might be null or undefined (though optional chaining obj?.property is now preferred in modern JavaScript). Unlike some languages that always return a boolean, JavaScript's logical operators return the actual operand value that determined the result.
