What is Mojo Python Superset?

What is Mojo Python Superset?

Python is among the most loved, popular, and powerful languages for programming complex applications from scratch. Its simple syntax is remarkably similar to English, making it a good choice for beginners. As a general-purpose programming language, it can help you interact with Database Management Systems (DBMS) and develop Back-End Servers. Most of its popularity comes from its vast range of out-of-the-box tools to get started in Data Science, A), and ML applications. Python is the golden tool that backs up the new, most revolutionary tool on the planet, ChatGPT!

There's only one pitfall about Python compared to low-level programming languages like C, C++, C#, and Java. Python is extremely slow, especially when it comes to large applications. That's a major roadblock for developing AI solutions. That's why a group of AI enthusiasts built Mojo, combining the flexibility of Python with the speed of low-level programming languages like C. That explains why they picked the name Mojo, considering it means "a magical charm." Let's dive deeper into the power of Mojo.

What is Mojo?

Mojo Lang, or just Mojo, is a new programming language to write systems-level code built by Modular, company owned by Chris Lattner, the creator of the Swift programming language and LLV, which is especially useful for building high-performance Machine Learning kernels, and accelerators. So, what does that have to do with Python? Modular built Mojo as a superset of Python, similar to TypeScript, a superset of JavaScript. To be blunt, you can think of Mojo as Python on steroids. Even that may be an understatement when you see that Mojo promises to be up to 35,000 times faster than Python in certain tasks. One of the coolest things about Mojo is that they didn't reinvent the wheel. Since they built Mojo on top of Python, Python code will be valid. Mojo can access Python's library ecosystem and tools like Pandas and Numpy.

How Does Mojo Work?

You must know much about this dynamic language to understand how it accomplishes high-performance codes. Mojo-specific features leverage the power of Multi-level Intermediate Representation (MLIR) without much complexity. In simple terms, MLIR is a powerful infrastructure for compile times that translates programming code into machine code. In other words, it takes Mojo code to a highly optimized format that various types of hardware can execute. That also allows Mojo to perform parallelization, a powerful technique that handles multiple tasks simultaneously. Python only allows for single-threaded execution, which causes great latency.

It will be much faster if you just run Python code in Mojo. But to get the most out of Mojo SDK, you must take advantage of its new amazing features. Like JavaScript, Mojo uses variable declarations like "let" and "var" to create immutable and mutable variables. Here's where things start to get interesting. Mojo also lets you implement progressive types in your code for improved performance. Like C and C++, Mojo can access pointers (no kidding) to take advantage of memory safety management. Also, like low-level programming languages, you can use strong type-checking and structs.

Why is Mojo Important?

The boom of Machine Learning and AI models quickly made Python one of the most important languages. However, Software Developers still had to lean on low-level languages like C/C++ and Rust. That explains why they used C and C++ to build Python libraries like Tensorflow and Numpy. If you're a Python programmer, these languages have a steep learning curve. The power of Mojo comes from letting developers combine the strength and speed of low-level languages with the flexibility of Python.

Plus, they don't have to learn a new programming language. Mojo provides safety and performance with strong types and efficient memory safety management. On top of that, it gives you the flexibility to be easy-going when required. One more cool thing to mention is that Mojo lets you get started with it using files ending in .mojo or .🔥 (fire emoji). Although it's already available on Linux Operating Systems, you can quickly begin with a web-based Jupyter Notebook environment. According to the official website, new releases will be available for Mac and Windows. Mojo's official release was in May, and it already has over 15k stars on GitHub, and over 120k have adopted it. So, there's a lot to expect from it.

Will Mojo Replace Python and C++?

All the buzz and excitement around Mojo is well-deserved. Combining the most popular programming language for AI and Data Science the power of the OG programming language features from contemporary Software Development is unreal. Hats off to the Modular team. However, we must consider that Mojo is a fairly recent tool still being developed. Python and C++ are mature programming languages with multiple applications. They go beyond AI and Machine Learning solutions.

Regarding C++, one of the OG programming languages with so many libraries and tools, it's fairly hard to think of another language replacing it. Since Mojo promises to keep the simplicity of Python, the community may split to some extent. As mentioned above, Mojo's adoption has been massive and pretty quickly. Many Python developers and enthusiasts are excited about Mojo. But since it's so new, we'll have to wait and see what unfolds.


For a tool that's still in its early stages, Mojo is formidable. There's no doubt that this beautiful language will help bring great Artificial Intelligence applications soon. Setting high expectations from someone who created the Swift programming language and the LLVM project is okay. Although they promised a 35,000x improvement compared to Python ecosystem, Mojo ended up being 68,000x faster after launch. We're very excited about Mojo and what it'll bring to the table of business applications!
