This function converts a single value (preferably a Lua table) into a JSON encoded string. You can use this to store the data and then load it again using fromJSON.
When using toJSON for submitting data using fetchRemote for example, make sure to use string.sub(data, 2, -2) to remove the brackets as many APIs will not understand the request
Due to technical limitations (partly of json-c) the stringified keys will be truncated to the first 255 characters
Syntax
