Javascript Debounce: React in 6 mins
Learn how *debouncing works in JavaScript and React* by building a real search example.
In this quick Concept Library video, we’ll look at how debounce prevents unnecessary searches while a user is still typing. Instead of firing an API request on every keystroke, we wait until the user pauses — then execute the search once.
We’ll cover:
How a debounce function works
`setTimeout` and `clearTimeout`
Why closures matter
Using `useRef` to preserve the debounced function between React renders
Tracking potential searches vs. searches actually executed
Applying debounce to a real React search component
The goal of the *Concept Library* is simple: one useful JavaScript or React concept, explained quickly and applied to real code.
*Wait for the typing to stop. Make fewer calls. Build a better search.*
