Im very curious if you used a certain coding language or did you use your own?

Scratch is not coded using scratch, but scratch was made using JavaScript.

More specifically, Scratch 3.0 was made using JavaScript, the primary language used on the web for programming things. There's also HTML (stands for Hypertext Markup Language), which is used to structure websites, and CSS (Cascading Style Sheets), which is used for making HTML look good.

Technically you only need HTML to make a webpage, but it won't be interactive (links will still work, but you can't make a game using HTML), and it will look bad.

Scratch 2.0 was made using ActionScript 3, the programming language used in the now-discontinued Adobe Flash player.

Scratch 1.4 was written in Squeak, a distribution of Smalltalk made by Disney Imagineering (the division of Disney responsible for all of the rides and much of the architecture in Disney theme parks), initially for internal use, and was later released to the public.

The source code for all versions of Scratch can be found at https://github.com/orgs/scratchfoundation/repositories

Scratch 3.0 is multiple different repositories, so pointing to one would be pointless. However, the main 3 that are generally considered the core of Scratch 3.0 are scratch-blocks (data about blocks, aside from their code for the most part), scratch-vm (the thing that runs your code), and scratch-gui (the Graphical User Interface for the editor). The website is scratch-www.

Scratch 2.0 is called “scratch-flash”

Scratch 1.4 is called "Scratch_1.4

A programming language cannot be made with itself.
KitKats’ filling is crushed KitKats.
However, the KitKat that comes first cannot be made with crushed KitKats because said crushed KitKats do not exist. And so therefore the KitKat that comes first is filled with chocolate and wafers.

Something’s first edition cannot be made with itself. Logically, that makes absolutely no sense.
