• Maintenance Cost: Languages with simpler syntax (Python, TypeScript) often reduce maintenance overhead. Complex or legacy languages (C++, older PHP) may increase long-term effort.
• Security: Memory-safe languages (Rust, modern C#) help avoid common bugs. Use languages with security libraries and strong typing to reduce vulnerabilities. Compliance frameworks favor .NET or Java due to built-in security/auditing.
• AI Tooling: Python and .NET have rich AI/ML libraries (e.g. TensorFlow, Azure AI) and benefit most from AI coding tools. JavaScript and Java also have growing AI toolkits. Low-level languages (C++, Rust) see less AI auto-completion support.
• WebAssembly Support: Rust and C# (via Blazor) compile to WebAssembly, enabling high-performance web apps. TypeScript/JavaScript run natively in browsers.
