Source: Codon: Python Compiler

Summary
Codon is a Python compiler that can produce native code that runs at or faster than hand-coded C/C++, but with limitations. Python and JS share performance limitations, such as every access to data or objects has to be type-checked, and they cannot process data in parallel.

Facts

🐍 Codon compiles Python into native code as fast, and sometimes faster, than C/C++.

🔍 Python and JS have to type-check every access to data or objects, which has an overhead of over 40% in Python.

🚀 JS is faster than Python because of its just-in-time (JIT) compiler that converts its code into faster machine code.

🐜 Python has the global interpreter lock (GIL), restricting it to a single thread at a time.
