JSON
IT Notes → Javascript @ December 22, 2020
- The object literal notation of JavaScript.
-
var myJSONObject = {key1: value1, key2: value2, key3: [{key4: value4, key5: value5}, {key4: value6, key5: value7}, {key4: value8, key5: value9}, ]};
- myJSONObject.key3 [0].key5 //value5
- var myObject = eval(‘(‘ + myJSONtext + ‘)’);
- var myObject = JSON.parse(myJSONtext, reviver);
JSON versus Eval:
- security issues.
- faster.
JSON does not support cyclic data structures.
- typeof value //To get typeof.
- var myJSONText = JSON.stringify(myObject, replacer);
