I am learning JS separately and was confused to run into setProperty(). Is that a custom property that code.org has created for the students? I wish they would state this because I would like to differentiate between whats vanilla JS and a library they use.
For instance, console.log() is vanilla JS, but they dont really differentiate.
Im actually more confused because you need to use dot notation when using setProperty I believe.
Code.org uses its own interpreter for the App Lab and Game Lab platforms. If you’d like to use vanilla JS, use Glitch.com, Replit.com, or Sololearn.com.
So they use a custom interpreter or library? For instance, in code.org there is a setScreen().
Is that considered a “function” that is from a code.org library? Or is that something else, I just dont know how to contextualize this to students.
I just call it a built-in function, since it is, well, a function.
It’s an interpreter. You write code that code.org translates into javascript to run. Libraries add on to the already existing code, such as jQuery in regular javascript - all it does is make some of the functions that previously exist more understandable, or easier to read.
tldr; interpreter: translates code, libraries: add onto code
Everyone is saying this. However, an interpreter in other aspects of computer science translates code into machine code, not into a higher-level language usually. Does code.org have documentation for this or anything?
Code.org doesn’t have its own documentation, but I’ve seen people somewhere else say that code.org is around 400x slower than vanilla JavaScript since it runs on its own interpreter.
Don’t exaggerate. It is 200x slower.
Jeez, sorry. I didn’t know the exact number.
Just kidding. But the guy who wrote the interpreter says 200x.
