cd

/siː-diː/

noun — “the magical command that teleports you around the filesystem.”

cd stands for “change directory” and is a fundamental command in UNIX, Linux, macOS, and Windows command-line interfaces. It allows users to navigate the file system by moving from the current working directory to another location, either by specifying a relative path or an absolute path. cd is often used alongside pwd, ls, and scripting operations to streamline workflows, file management, and automation.

React-Router

/riˈækt ˈruːtər/

n. “Maps your components to the URL without breaking a sweat.”

React Router is a declarative routing library for React, allowing developers to build single-page applications (SPAs) with multiple views that respond to changes in the URL. Unlike traditional page reloads, React Router enables seamless navigation while keeping the application state intact.
