Hi Hive account@heejin,

Sorry, I'm confused a little:)
If I never change Object.prototype in my code, should i still check for hasOwnProperty?

I'll might going to use Object.keys() as it is really looks simple but first I want to understand if I'm in danger that something changes my Object without I'm asking for it, or not?

Edit: I got it now, "You can easily modify Object.prototype" So it is me, who accidentally changing it! My question was lame:)
