Standard Library
Noun · Development
Definitions
The collection of modules, functions, and types that ships with a programming language and is available without installing external packages — such as Python's os, json, and http modules, Go's net/http and fmt, or Rust's std crate. It defines the baseline capabilities and idioms of the language ecosystem.
In plain English: The built-in toolbox of ready-to-use code that comes included with a programming language, no extra downloads needed.
Example: "Don't pull in a third-party library for that — Go's standard library has a perfectly good HTTP server and JSON encoder built in."
