What are common pitfalls with objects?

Exploring the common pitfalls of JavaScript objects can help developers write more efficient and error-free code. This article discusses several issues, including prototype pollution, mutable references, and the dangers of using global objects. Understanding these challenges can enhance your coding practices.

// Example of a common pitfall with objects const user = { name: 'Alice', age: 30, }; // Mutable reference pitfall const userCopy = user; // userCopy now references the same object as user userCopy.age = 31; // This will also update user.age console.log(user.age); // Output: 31, which might not be the intended effect
