2. What is Mojo?
● A new programming language for AI developers
● Mojo is a programming language that combines the ease of use and flexibility of dynamic
languages, such as Python.
● It has performance and control of systems languages, like C++ and Rust.
● .Mojo is a programming language developed by Modular Inc.
● It was made accessible by browser in May, 2023 and locally on Linux in September, 2023.
3. Key Features?
● Python-like syntax and dynamic typing: Mojo has a syntax that is similar to Python, making it easy for Python developers to learn.
Mojo also supports dynamic typing, which means that you do not need to declare the type of each variable before you use it.
● Systems programming features: Mojo also includes a number of systems programming features, such as manual memory
management and support for multiple threads. This makes Mojo suitable for writing high-performance and resource-efficient code.
● Metaprogramming.
● Portability.
● High performance.
● Interoperability with Python: Mojo can import and use any Python library, giving developers access to a vast ecosystem of tools and
resources. This makes Mojo a good choice for developers who want to use the latest AI and machine learning techniques without
having to learn a new programming language from scratch.
● Mojo is a promising new programming language with the potential to revolutionize the way AI and machine learning software is
developed.
● Mojo is still under development, but it is already being used by a number of companies and researchers to build cutting-edge AI and
machine learning applications.
4. Syntax Example
This is simple: Mojo supports all of Python’s syntax and semantics. If
you’re not familiar with Python syntax.
For example, like Python, Mojo uses line breaks and indentation to define
code blocks (not curly braces), and Mojo supports all of Python’s control-
flow syntax such as if conditions and for loops.
fn main():
print("Hello, world!")
Main()
This program is very similar to the "Hello, world!" program in Python. The
fn main() statement defines a function called main(), which is the entry
point for the program. The print("Hello, world!") statement prints the
message "Hello, world!" to the console.
5. Syntax Example
Run a Mojo file
First, write the Mojo code and execute it:
Create a file named hello.mojo (or hello.🔥) and add the following code:
fn main():
print("Hello, world!")
That’s all you need. Save the file and return to your terminal.
Now run it with the mojo command:
mojo hello.mojo
It should immediately print the message:
6. Syntax Example
In the example, we will create a Mojo function
that will add two arguments.
To run the Mojo function:
You must specify a type to arguments of the
function.
You must declare the return type with an
arrow.
fn add(x: Int, y: Int) -> Int:
return x + y
z = add(3, 5)
print(z)
7. Language basics
First and foremost, Mojo is a compiled language and a lot of its performance and
memory-safety features are derived from that fact. Mojo code can be ahead-of-time
(AOT) or just-in-time (JIT) compiled.
Like other compiled languages, Mojo programs (.mojo or .🔥 files) require a main()
function as the entry point to the program. For example:
fn main():
var x: Int = 1
x += 1
print(x)
If you know Python, you might have expected the function name to be def main()
instead of fn main(). Both actually work in Mojo, but using fn behaves a bit differently.
8. Data Types
Mojo is a statically typed programming language, which means that you must declare
the type of each variable before you can use it. This helps to prevent errors and
makes your code more reliable.
Mojo has a number of built-in data types, including:
Int: Integer numbers.
Float: Floating-point numbers.
Bool: Boolean values (true or false).
String: Text strings.
Char: Single characters.
Void: The absence of a value.
9. Functions
● Mojo functions are similar to functions in other programming languages. They allow
you to group together related code and reuse it throughout your program.
● To define a function in Mojo, you use the fn keyword followed by the name of the
function and a list of parameters. The body of the function is defined between curly
braces.
● Both fn and def functions have their value.
● fn functions enforce strongly-typed and memory-safe behaviors in your code
