What does "hydration" mean in programming?
hydration is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
The process where a JavaScript framework takes over a server-rendered HTML page and makes it interactive by attaching event listeners and initializing state. Hydration bridges server-side rendering and client-side interactivity.
Example
"Hydration errors occur when the server-rendered HTML does not match what React expects to render."
