There is another use case for parseConsoleRemoteObject, which is when JSONValue is called. At the moment this API uses valueFromRemoteObject which returns a goja.Value. Interestingly, the return value is always converted to string before being returned to the caller, so the extra step to convert to goja and then back to string is not needed.
Just wanted to clarify this with a comment that the browser module does capture other log types other than the usual info, warn, error and debug, such as console.table, but it defaults to debug.
JSONValue was using valueFromRemoteObject which returns a goja.Value but then converts that back to a string. This conversion is: 1. unnecessary, and it should just work with parseConsoleRemoteObject which returns a string. 2. dangerous since it could be called off the main goja thread (i.e. in a new goroutine or promise) which could cause unwanted panics since goja runtime should only be used on the main goja thread.
Instead of panicking which can cause unexpected side affects, return an error.

JSONValueto useparseConsoleRemoteObject.Why?
This will help avoid working with the goja runtime outside of the mapping layer and therefore avoid possible race conditions with the unsafe goja runtime.
JSONValuewasn't ever working with the goja values and so it made sense to always work with string values.Checklist
