Convert a value to JSON, optionally replacing values if a replacer function is specified, or optionally including only the specified properties if a replacer array is specified.
Convert a value to JSON, optionally replacing values if a replacer function is specified, or optionally including only the specified properties if a replacer array is specified.
The value to convert to a JSON string.
If a function, transforms values and properties encountered while stringifying; if an array, specifies the set of properties included in objects in the final string.
Causes the resulting string to be pretty-printed.
