Developers who wants high-performance computing and scientific programming have a few languages to turn to for help. Thank God for Julia, Mojo, and C++, they are languages that is dominating now . We are going to compare both Mojo Julia and C++ to know their speed , fastness and how they actually work.
Overview of Julia, Mojo, and C++.
What is Julia?
The Julia is a high-level, high-performance programming language, that is developed specially for numerical and scientific computing. Julia has a greater speed than python and with the velocity of compiled languages like C and Fortran. Julia is currently one of the most popular languages in this area: data science, machine learning, and scientific simulations.
What is Mojo?
Mojo is a new programming language that is easy to write like Python. But the only thing is that it has the raw and unbridled performance of low-level languages like C++. It is highly optimized for supercomputing, artificial intelligence, and machine learning. Mojo is like Python-like syntax. This makes it quite familiar and friendly to most developers who know Python Very well. However, mojo is really high in performance for a computational intensive tasks.
What is C++?
C++ is one of the most reliable, general-purpose programming languages. C++ is significant in the software development industry over several decades. It is an extension to the C programming language which includes some object-oriented features. it is considered efficient, flexible, and capable of handling system resources efficiently. C++ finds its main applications in system programming, game development, and high-performance applications.

Speed and Performance
Julia Performance
Julia stands out when it come to high performance, especially in numerical/scientific computing. It is a JIT compilation. This means that independent of the language syntax one uses. The code is written and then translated into quite effective machine code. Performance usually ranges very close to C or sometimes even Fortran. Its multiple dispatch and the ability to effectively handle complex math make Julia ideal for technical computing.
Mojo Performance
The aim of Mojo is to match the performance of C++ without losing the usability of Python. It targets high-performance computing in AI and machine learning . It makes Mojo competitive in areas using huge amounts of computational power.
C++ Performance
C++ has won respect for its high speed and efficiency. It is the language of everybody when it comes to system-level programming and millisecond applications. C++ opens greater opportunities for optimization at lower levels and control over system resources. It is also hence popular in high-performance-oriented areas such as gaming, financial systems, and real-time simulations.
Speed Comparison
Execution Speed : C++ has the best execution speed because of its low-level nature and fine-grained control over system resources. Julia and Mojo also have good performance but not like c++. Julia does well in numerical computations and Mojo does well in artificial intelligence and machine learning.
Compilation Speed : C++ compilation times can be long, especially for large projects. Julia uses JIT compilation, which may add the first run latency but gives fast execution afterwards. In the case of Mojo, it is compile-time effective.
