Depends on your priorities. If performance is your absolute driving characteristic, then by all means use the fastest one. Just make sure you have a full understanding of the differences before you make a choice Unlike serialize() you need to add extra parameter to keep UTF-8 characters untouched: json_encode($array, JSON_UNESCAPED_UNICODE) (otherwise it converts UTF-8 characters … Read more
Use the second parameter of json_decode to make it return an array: $result = json_decode($data, true);
To find the maximum y value of the objects in array: Math.max.apply(Math, array.map(function(o) { return o.y; })) or in more modern JavaScript: Math.max(…array.map(o => o.y))
Jackson provides an annotation that can be used on class level (JsonIgnoreProperties). Add the following to the top of your class (not to individual methods): @JsonIgnoreProperties(ignoreUnknown = true) public class Foo { … } Depending on the jackson version you are using you would have to use a different import in the current version it … Read more

Use the pretty_generate() function, built into later versions of JSON. For example: require ‘json’ my_object = { :array => [1, 2, 3, { :sample => “hash”} ], :foo => “bar” } puts JSON.pretty_generate(my_object) Which gets you: { “array”: [ 1, 2, 3, { “sample”: “hash” } ], “foo”: “bar” }
There are 94 Unicode characters which can be represented as one byte according to the JSON spec (if your JSON is transmitted as UTF-8). With that in mind, I think the best you can do space-wise is base85 which represents four bytes as five characters. However, this is only a 7% improvement over base64, it’s … Read more
PHP 5.4 offers the JSON_PRETTY_PRINT option for use with the json_encode() call. http://php.net/manual/en/function.json-encode.php <?php … $json_string = json_encode($data, JSON_PRETTY_PRINT);
Use a JSON parser like JSON.parse: function isJsonString(str) { try { JSON.parse(str); } catch (e) { return false; } return true; }
Use the ensure_ascii=False switch to json.dumps(), then encode the value to UTF-8 manually: >>> json_string = json.dumps(“ברי צקלה”, ensure_ascii=False).encode(‘utf8’) >>> json_string b'”\xd7\x91\xd7\xa8\xd7\x99 \xd7\xa6\xd7\xa7\xd7\x9c\xd7\x94″‘ >>> print(json_string.decode()) “ברי צקלה” If you are writing to a file, just use json.dump() and leave it to the file object to encode: with open(‘filename’, ‘w’, encoding=’utf8′) as json_file: json.dump(“ברי צקלה”, json_file, … Read more
