This review talks about properties and methods of objects. On the surface (judging by how they look in the code), these look very much alike. the only difference I can spot is that a property like .length lacks the parantheses that a method like .toUpperCase() has.
What’s the exact difference between properties of an object and its methods?
Is there one on a technical level (the computer does different things with either) or is it a rather “human” distinction (only we can tell the difference, the computer can’t)?
I was asking myself the same thing yesterday. I found a post on a website that made me understand
" Think of an object as an object in real life (such as a bicycle). A method is something you can do with the bike (pedal), or something you can do to the bike (re-inflate tire). A property is something about the bike: how many wheels it has (wheels) or its height (height).
What is an instance of a datatype? What is meant by instance?
In the review page it reads
Objects, including instances of data types, can have properties, stored information. The properties are denoted with a . after the name of the object, for example: 'Hello'.length .
Objects, including instances of data types, can have methods which perform actions. Methods are called by appending the object or instance with a period, the method name, and parentheses. For example: 'hello'.toUpperCase() .

There are 8. They forgot to add BigInt to the review. Do we just need to comment here for them to update that or is there a different process that we need to do in order to submit change requests?
