Which answer is correct?

Use `JSON.stringify(a) === JSON.stringify(b)`. This converts both to strings and compares.

— json_fan

Use `Object.is(a, b)`. This is the correct way to compare objects in modern JS.

— modern_dev

Write a recursive deep equality function, or use a well-tested library like Lodash's `_.isEqual()`. There is no built-in deep comparison in JavaScript.

— thorough_dev

Use `==` instead of `===`. The loose equality operator handles object comparison better.
