Leverage Libraries for Language Development

Deliberate decisions to maintain a foundational architecture, rather than overhauling it, have facilitated the evolution of programming languages. LLVM, which stands for Low Level Virtual Machine, presents components of a compiler as a library, making it simpler for language developers to integrate pre-built optimization passes and code generators. This modularity allows languages like Rust to target multiple architectures, such as Intel, ARM, and RISC-V, without starting from scratch. Consequently, there is a shift in focus towards developing languages that are easier to implement, primarily due to the comparative simplicity of writing interpreters over compilers.
