I came across a JavaScript package called Seroval, which helps with serializing or converting JavaScript objects into strings. Since I'm not very experienced with this, I'm curious about when and why someone would actually need something like this. I've never really had to deal with complex objects or values like recursive objects or cyclic references, so I'm struggling to find potential use cases. Can anyone share some examples of how this might be useful?

I've actually used something like Seroval for transferring code between a Node process and a headless browser process (like Puppeteer) for testing purposes. It simplifies the task of sending complex data between different environments.
Serialization is crucial for data transmission. You can't send complex objects over the network without breaking them down into simple strings of bits, and that's where serialization tools come in handy. It enables the smooth passing of data between systems.
If you've ever worked with Axios, you'll understand the need for a tool like this. Sometimes, you encounter response objects that reference request objects, creating a cycle that makes it impossible to stringify without a solution like Seroval. It helps avoid those infinite loops during serialization!
That makes sense! But can you share a scenario where you actually had to stringify a Request or Response object? I'm just trying to grasp when that would be necessary.
