React tldr; Optimize Components with React.memo, useMemo, and useCallback

maniekm profile image Mariusz Updated on ・1 min read
  • With React.Memo, if a component returns the same result given the same props, wrapping it in memo can result in a performance boost.

  • useMemo allows you to memoize the results of a function and will return that result until an array of dependencies change.

  • useCallback can prevent unnecessary renders between parent and child components.
