Profiling i noticed (in my case) jsJson is called over 10k times in the code, causing wall time to be quite high.
On large strings
json_decodeis a heavy operation, if we perform some simpler string checks we can hopefully reduce some json_decode operations.once https://www.php.net/manual/en/function.json-validate.php can be used this can further optimise the check since it's what json_decode uses before actually attempting to decode, thus we can skip the decoding itself.
