Duplicate property names in object literals

This is a Sonar rule that makes sure the JSON structure has quality built-in.

Sample JSON:

var data = {
    "key": "value",
    "key": "value2", // not compliant
    key: "value3" // not compliant
}

In this case, data.key will be “value3” (taking the last instance).

JavaScript allows you to do this, it is valid javascript, but it only takes the last instance. This makes the code hard to debug and prone to bugs since a developer unfamiliar with the nls file or whatnot will assume the first Ctrl-F found item is the only instance.
