In your code, a for loop is used but the key is ignored... and the check for EN or CN should be || (or), not && (and).

To Update content_available as true for code (EN, CN), the code should be:

 function setContentAvailable() {
   for (var key in myObj.data) {
     if (myObj["data"][key]["code"] === "EN" || myObj["data"][key]["code"] === "CN") {
         myObj["data"][key]["content_available"] = true;
     }
   }
 }
 setContentAvailable();
