How to Handle Circular Structures in JSON?

JSON serialization encounters limitations with circular structures. To handle this, we delve into an alternate approach that excludes circular references.

In JavaScript, the built-in util.inspect function can come to our rescue. It identifies and replaces circular references with the placeholder "[Circular]."

To employ _util.inspect_, follow these steps:

1. Import the utility as either * as util from 'util' or { inspect } from 'util'.
2. Utilize the inspect function with the syntax util.inspect(myObject).
3. To customize the output, pass an options object containing parameters like showHidden, depth, and colors.

// Example usage
console.log(util.inspect(myCircularObject));

This method allows for converting circular structures into JSON-like formats while preserving the core data. It's particularly useful for debugging and troubleshooting in development environments. By selectively excluding circular references, you can obtain a representation that's suitable for communication.
