How to Compare JSON Objects

If you have ever tried objA === objB in JavaScript, you know it compares references, not values. To compare the actual data within two JSON objects, you need deep equality.

The Stringify Hack

Many developers use JSON.stringify(objA) === JSON.stringify(objB). While fast, this breaks if the keys are in a different order.

For robust applications, using a dedicated JSON Diff tool or library like Lodash's isEqual is the only safe approach.
