Alright kiddo, let's talk about something called obj in programming language.
So imagine you have a toy box filled with different toys like blocks, dolls, and cars. Now let's say you want to play with your toy car. You would need to take it out of the box and use it, right?
Well, in programming, "objects" are kind of like toys in a toy box. They are little pieces of code that have different properties and things they can do. So just like you would take out your toy car to play with it, a programmer would need to use objects in their code to do different things.
Now, the "obj" part of this refers to a specific file format used for objects in some programming languages. It's short for "object file" and it basically means that all the information about an object is stored in a certain way in a file.
Think of it like a little toy car being stored in a specific box with all its parts and pieces organized in a certain way so you can easily find everything you need.
So when a programmer uses an object in their code, they might use an "obj" file to easily find and use all the information they need. It's like having a little toolbox with all the parts you need to build something.
But of course, just like there are many different types of toys in a toy box, there are many different types of objects in programming, and not all of them use the "obj" file format. It just happens to be one way that some programming languages store information about their objects.
