JavaScript JavaScript Loops, Arrays and Objects Tracking Data Using Objects The Object Literal

Should Objects also be declared using let or const?

Just to be sure. I have learned that var is obsolete for declaring variables or arrays. Is the same thing true for objects?

It is widely accepted that var declaration shouldn't be used at all by this point. Const or let should be used for declaring ANY data type variables and even functions. You should be choosing which one to use based only on the lifecycle and scope of your variable. However if you want to get deeper into the topic, I'd suggest reading up this article:

Just to add a note to Wiktor Bednarz response, you'll find that with ES6, objects are more and more being created using Classes. You can have a quick read on classes here.

That was a great question for the Community. Thanks for asking it! :)
