Are you ready to supercharge your AI development skills? 🚀 Dive into the world of Mojo, the programming language that's taking the AI community by storm! In this post, we'll give you a sneak peek of what Mojo has to offer, along with some snippets from the Mojo Cheat Sheet. For the full scoop, make sure to check out the complete Mojo Cheat Sheet on my blog.

Mojo REPL - Your Playground for Quick Testing:

Mojo comes with a built-in REPL (Read-Eval-Print-Loop) that allows you to quickly test your code. To start the REPL, simply type mojo in your terminal:

$ mojo
Enter fullscreen mode Exit fullscreen mode

Hello World - Your First Mojo Program:

Let's begin with the classic "Hello World" program in Mojo:

print("Hello World!")
Enter fullscreen mode Exit fullscreen mode

Mojo's syntax is reminiscent of Python, making it welcoming to developers of all backgrounds.

Variables - let vs. var:

Mojo provides two ways to declare variables. Use let for variables that can't be reassigned and var for those that can be reassigned:

let x = 10  # x can't be reassigned
var y = 20  # y can be reassigned
Enter fullscreen mode Exit fullscreen mode

Functions - Declaring and Calling:

Define functions in Mojo using the fn keyword and call them effortlessly:

fn add(x: Int, y: Int) -> Int:
  return x + y

fn main():
  let x = 10
  let y = 20
  let z = add(x, y)
  print(z)  # 30
Enter fullscreen mode Exit fullscreen mode

Structures - Your Blueprint for Custom Types:

Mojo's structures are similar to Python classes, supporting methods, fields, and metaprogramming:

struct Car:
  var mileage: Int
  var tires: Int

  fn __init__(inout self, mileage: Int, tires: Int):
    self.mileage = mileage
    self.tires = tires
Enter fullscreen mode Exit fullscreen mode

Integration with Python - Harnessing the Power of Both Worlds:

Mojo seamlessly integrates with Python, enabling you to import Python modules and create Python types from Mojo types:

from python import Python
let np = Python.import_module("numpy")  # Import numpy from Python
let array = np.array([1, 2])
Enter fullscreen mode Exit fullscreen mode
