Even though I'm not a fan of go myself, it does work well for small, simple utilities - it's lightweight, fast, and compiles to self-contained executables, with no dependency on a runtime like Node.js, Python, or a JRE.

There are some other languages that have similar benefits, but go is the most popular and trendy. Rust could fill a similar niche but GC is very nice and Rust definitely has a higher learning curve.
