What is the result of this code? const obj = { a: 1 }; Object.freeze(obj); obj.a = 2; console.log(obj.a);

Accepted Answer

Object.freeze makes an object immutable, meaning properties cannot be added, removed, or changed. In non-strict mode, assigning a value to a frozen property fails silently, leaving the original value intact. In strict mode, it would throw a TypeError. Since the question does not specify strict mode, the silent failure is the standard behavior, resulting in 1 being logged.
