Function isSerializable

Returns boolean

True if serializable; false otherwise

Note: the values undefined and null are serializable (on their own or in an array), but null values get transformed into undefined when serializing/deserializing.

WARNING: This is inefficient right now as it stringifies, parses, stringifies, and === the value. Please only use this if you need to

DISCLAIMER: this does not successfully detect that values are not serializable in some cases:

• Losses of removed properties like functions and Maps
• Class instances (not deserializable into class instances without special code)

We intend to improve this in the future if it becomes important to do so. See JSON.stringify documentation for more information.
