Context

/ˈkɒnˌtɛkst/

n. “Sharing state without prop-drilling chaos.”

Context in React is an API that allows data to be passed through the component tree without manually passing props at every level. It is designed to solve the problem of “prop-drilling,” where intermediate components receive props only to pass them down to deeper components that actually need the data.

Redux

/ˈriːˌdʌks/

n. “Predictable state. Fewer surprises.”

Redux is a state management library for JavaScript applications, most commonly used with React. Its core purpose is to centralize application state, making it predictable, traceable, and easier to debug. In complex applications, juggling state across multiple components can quickly become chaotic — Redux offers a structured solution.
