MOJO MIJIA Guide to Mojo Programming Language

from A Pythonista's Perspective

Run the code while you read

Throughout the Miji, every Mojo code block that forms a complete program has a Run button at the right end of its header line, beside the name of the language. Click it, and the program is compiled and executed for you, with the output appearing right below the code. You can also click the code itself and change it, so you can try your own ideas without leaving the page.

def main():
   a = "Hello, world!"
   print(a)

   b = 0
   for i in range(10):
      b = b + i
   print(b)
