Real world examples?

Question

So in the real world, how is javascript actually used? Where are things like arrays or objects actually used? Why are they used?

All I've seen on the internet is how to create arrays or objects, but not once have I seen or heard about real world uses for them.

Answer 3

Hello, Daniel Cooper !
Arrays are the same objects, but with their methods and chips (Uncle Array's children), such as length, sort, join, splice, slice, etc.

They have a clear order, because the keys are represented as consecutive numbers. And this is the main reason for using them - they can be shredded, sorted, and added into them new values ​​at certain points.

In fact, ["A", "B", "C"] can be represented as a new Array ("A", "B", "C") and hence as {0: "A", 1: "B", 2 : "C"}.

Answer 6

Array and object are used a lot on Javascript especially in API access, All api data is formatted in objects and arrays form.

You also use Javascript array to populate your data (from api) to class element eg. getElementsByClassName("clsname") array or table td elements.

You use object in modular object oriented programming to initiate all class modules.
