Codebase
ELI5 — The Vibe Check
The codebase is the whole collection of source code that makes up a project — every file, folder, and line of code. When someone says 'familiarise yourself with the codebase', they mean 'read through the project until you understand how it all fits together'.
Real Talk
A codebase is the complete body of source code for a software project or system, stored in a version control system. Understanding the codebase structure — its modules, conventions, and patterns — is essential for contributing effectively.
When You'll Hear This
"The codebase is huge — start with the core modules." / "Technical debt has accumulated across the entire codebase."

Linter
A linter is the code police — it automatically checks your code for style violations, bad patterns, and potential bugs without running it.
Monorepo
A monorepo is when you put all your different projects — frontend, backend, shared libraries — in one giant single repository instead of separate repos.
Open Source
Open source means the recipe is public. Anyone can read it, copy it, tweak it, and share their version. It's the opposite of a secret sauce.
Refactor
Refactoring is cleaning and reorganizing your code without changing what it does — like tidying your room without throwing anything away.
Workspace
A workspace is how package managers understand a monorepo — they see multiple packages inside one repo and manage them together.
