What Does ‘Read the Documentation’ Really Mean?

When folks mention "documentation," they generally mean the user manuals for different languages or libraries. For example, the Python documentation has everything you need to know about using the language: https://docs.python.org/3/.

To me, 'documentation' refers to quick, succinct explanations of functions, classes, and commands in a language or library. For Python, you can find all the built-in functions documented here: [Built-in Functions — Python 3.14.2 documentation](https://docs.python.org/3/library/functions.html). If you forget how something like 'range' works, just look it up in the documentation for a fast refresh!

Official documentation usually contains two parts: a user guide and a reference manual. As a newcomer, the user guide is super helpful; it provides examples and clarifies how everything works. The reference manual, while useful, can be overwhelming because it's often organized alphabetically. If you're diving deep into a language for a job or personal project, it's wise to skim the reference manual too. For JavaScript, check out MDN (https://developer.mozilla.org/) and Node.js docs (https://nodejs.org/api/all.html). Pro tip: don't skip the performance chapter—it's crucial for effective coding!
