The IDE is recommending that you add a test:
if (awards.hasOwnProperty(i)) {
...
}
inside the for loop.
I personally recommend not doing this, and disabling the warning if possible. There’s simply no need in most code, and even less need in ES5 code where you can safely add non-enumerable properties to an object using Object.defineProperty
The hasOwnProperty check is only necessary if you have unsafely added new (enumerable) properties to Object.prototype, so the simplest fix is don’t do that.
jQuery doesn’t perform this test – they explicitly document that jQuery will break if Object.prototype is unsafely modified.
