JSON undefined value type
json
Solution
undefined is not a valid JSON value, even though it is valid in javascript.
From the official JSON standard (ECMA-404, Section 5):
A JSON value can be an object, array, number, string, true, false, or null.
For JSON, use null instead of undefined: `{ "something": null }`
Problem
I came across this JSON code. I noticed that it makes use of `undefined` value. Where can I find more information about this value type? ``` tracks:[ ( { codec:"h264", language:undefined, id:1, bitrate:785236, content:"video" } ), ( { codec:"aac", language:undefined, id:2, bitrate:75969, content:"audio" } ) ], ```
