/** * @brief * Mass Update certain key-values recursively in huge, complex JSON string trees * @author Andrew Kang * @param original string required (must be JSON string) * @param key string required * @param value string or boolean or number or null required * @return string */ // IMPORTANT : the variable 'original' should be valid JSON. // You can test your JSON string source like here. // https://jsonformatter.curiousconcept.com/ var result = Pattern.sculptJson(original, 'Mike{[Gentleman]}', null); // You can convert the result string to an object type. var resultObj = JSON.parse(result); [Original source]
var original =
