Why Scratch and Not Python, JavaScript, or C?

Scratch -

Python - print("Hello World!")

JavaScript - alert("Hello World!");

C -

#include <stdio.h>

int main()

{

// printf() displays the string inside

quotation

printf("Hello World!");

return 0;

}

Hello World!

Learning Environment), a GUI toolkit, an interpreter, or a compiler.

Everything is free and built right into the website interface.

Best for grades 3 - 5.
