Julia is a general-purpose open-source programming language that debuted in 2012, prioritizing ease of use and execution efficiency. In this paper, we explore Julia’s potential in the insurance industry by contrasting its capabilities with other popular languages including Python, Rust, .NET (C#), and C++, focusing on development efficiency and processing performance. We also introduce Mojo, a new programming language released in 2023. We discuss:  

• What is Julia?
