    Returns a memoized value.

    Pass a “create” function and an array of dependencies. useMemo will only recompute the memoized value when one of the dependencies has changed. This optimization helps to avoid expensive calculations on every render

    Library: react

    Shortcut: react.hook.memo.use

    import { useMemo } from "react";
    
    const memoizedValue = useMemo(() => { 
      return computeExpensiveValue(dependency1, dependency2) 
    }, [dependency1, dependency2]);
