Object keys, values, and entries methods

This video covers three Object methods - keys( ), values( ) and entries( ).
All three methods will create an iterable Array from the Object that you can then use in conjunction with other Array and iterable methods.

Dude, straight to the point. Everything I needed, and although simple it was so hard to find it all compiled in one go like that. Go Canada!

[@kris8536]

Steve, you helped me solve in 2 minutes what I have spent the last hour on. THANK YOU!

[@daeroi3116]

I really needed this. Concise, clear, straight to the point, and easy to understand. I don't get why free TH-cam videos break down concepts way better than courses I had to go and pay for. Thanks a lot.

[@vladimirzizic6874]

I didn't think I even needed any further clarification on objects and arrays until I came across this video. This was perfectly explained.

[@meraatmostafavi7758]

thanks a lot

[@christmasvillage3652]

lol I am guessing that you may be a fan of Game of Thrones? Nice explanation of the three functions for object. Thank you so much.

[@jp-hz6br]

How do you change the name of a key. Say, if I wanted to add an ‘s’ character onto the end of keys that held array objects as their values?

[@SteveGriffith-Prof3ssorSt3v3]

You cant change the name of a key. You can create a new key, copy the value of the old key to the new key and then delete the old one.

[@anshulmanapure1980]

Steve, this work of yours is gold. Truly.
Edit: One doubt though. What if we had an anonymous function as a value of some key inside an object. What happens to that? I'm fairly new to JS and programming in general, but I haven't saw we declaring a function inside an array.

[@SteveGriffith-Prof3ssorSt3v3]

The values assigned to the keys in an object can be anything, including an anonymous function.
Functions in JavaScript are first class citizens. They can be passed around like any variable.

[@alexhitchins4339]

FANTASTIC!!! Such a good explanation. Thank you very much!

[@sterling3419]

A fellow GOT fan

[@davidgriffin7632]

Could you give any advice on how you'd access a specific entry without knowing the index number? Like if you were wanting to log 'Snow' without knowing it is [2][1], but you knew the key was 'jon'.

[@SteveGriffith-Prof3ssorSt3v3]

The key concept is accepting the fact that objects are not built with sequential properties. There is no number associated with the properties. Object.keys() gives you a list of the possible properties. Don't think of it as the order of properties.

[@oghenefokethompson7407]

Thanks sir

[@bribes_for_nouns]

So say we convert an object to an array so we can use methods on it easier. After doing this, how would we convert the newly updated array back into the object that it came from?

[@SteveGriffith-Prof3ssorSt3v3]

We wouldn't. We would have the original object plus the new information we got from the array methods.

[@KishoreKumarmaistry]

Dock Adams if it's a two dimensional array, then we can use the Object.fromEntries(arr) to convert back to object

[@tyeellis1046]

Nice
