Just to interject one bit... I actually really like JS/TS for basic data transformations, piping and ETL type work in general. If you understand how type coercion works with JS it can be really powerful as a tool for these types of workloads.

Meanwhile, for actual low-level work data is bytes not Javascript objects in memory, and Javascript is a miserable tool for transforming/processing bytes.
