海外TECH	DEV Community	The React useMemo Hook Made Simple	https://dev.to/alexdevero/the-react-usememo-hook-made-simple-5c8d	The React useMemo Hook Made SimplePerformance is important especially in large scale application The React useMemo hook is one tool you can use to improve the performance of your React apps This tutorial will help you understand what useMemo hook is and how it works It will also show you how to use it Introduction to React useMemo hookThe React useMemo hook is one of the additional hooks that are implemented in React All these hooks serve different purposes The purpose of useMemo hook is to memoize the output of a function What this means is that it executes some function and remember the output of that function The important part comes when your component re renders After re render any function in the component would be normally created If you are also calling the function it would be also executed again The useMemo hook helps you avoid this It allows you to execute the memoized function only under specific conditions When these conditions are not met the useMemo will not execute the function Instead it will return the value from the last execution This simple thing can help you optimize your React application by avoiding expensive calculations every time one of your components re render When you think about it the useMemo hook is a bit like the useCallback hook Both use memoization The main and maybe only difference between these two is that while useCallback hook helps you memoize whole function the useMemo helps you memoize only the output of functions The syntaxThe React useMemo hook accepts two parameters These parameters are some function whose output you want to memoize and array of dependencies The useMemo hook will execute the function you passed as an argument after the initial render by default Import useMemo hook from React import useMemo from react export default function App useMemo syntax example const memoizedVal useMemo gt Some function Dependencies return lt div className App gt lt div gt When to runWhen the useMemo hook runs and executes the function you passed is determined by the second argument the hook accepts the dependency array By changing this argument you change when the hook runs There are currently three options No Only after initial renderThe first option is to run the hook only after the initial render and never again Then when something causes the component to re render useMemo will not execute the function again Instead it will return the memoized output of the function It will do this for every subsequent re render If this is what you want you have to specify the dependency array as empty This means that there are no values the useMemo hook should watch It should always return the memoized output Import useMemo hook from React import useEffect useMemo useState from react export default function App Create state for count const count setCount useState Create computationally expensive function const fibonacci num gt return num num fibonacci num fibonacci num Memoize fibonacci function const memoizedVal useMemo gt fibonacci count Above the dependency array is empty The useMemo will run only once Check if memoizedVal changes useEffect gt This log will show only once because useMemo will run only once console log memoizedVal memoizedVal return lt div className App gt lt p gt count lt p gt lt button onClick gt setCount prevCount gt prevCount gt Increase count lt button gt lt div gt The example above demonstrates that useMemo runs only after initial render It will generate fibonacci number for the initial value of count state When you increase the count by clicking the button value of count will increase You can see this change in the paragraph above the button However no log will show up This is because the useMemo hook will not run the fibonacci function again It will return the same value you got after the initial render Since the value of memoizedVal is the same the useEffect hook will not execute the console log Remember it watches only the memoizedVal No Only when dependency changesThe second option is to run useMemo and execute the function you passed again when specific value changes This will be useful when the function you passed as an argument accepts some value from the outside When this outside value changes you may want to re calculate the output so the output is correct To do this you have to specify the value you want to watch as one of the dependencies useMemo will then watch this value and execute the function you passed every time the watched value changes If it doesn t change useMemo will return the memoized value value from the last execution There is no limit to how many dependencies you can specify for the useMemo hook If you want the hook to watch one specify one If you want it to watch specify all ten Just make sure to specify all dependencies you need and omit those you don t need Otherwise useMemo will re execute the function too often or not often enough Import useMemo hook from React import useEffect useMemo useState from react export default function App Create state for count const count setCount useState Create computationally expensive function const fibonacci num gt return num num fibonacci num fibonacci num Memoize fibonacci function const memoizedVal useMemo gt fibonacci count count Above the count is specified as a dependency When the value of count changes useMemo will run and execute fibonacci function Check if memoizedVal changes useEffect gt console log memoizedVal memoizedVal return lt div className App gt lt p gt count lt p gt lt button onClick gt setCount prevCount gt prevCount gt Increase count lt button gt lt div gt In the second example the useMemo watches the count value because it is specified as a dependency Because of this useMemo runs every time the count value changes and executes the fibonacci function Every change of count also changes the input of the fibonacci function and also the output it returns Since execution of fibonacci function changes the memoizedVal this also causes the useEffect hook to execute the console log As a result new message with new value shows up in the console No After every re renderThe last option is to tell useMemo to re run the function you passed on every re render This is kind of a nonsense There is no reason to use useMemo to memoize something just to actually never memoize it However since this is possible it is still an option Warning don t do this It is dumb and waste of time Anyway Let s say you are in a situation where this is the only option which is incredibly unlikely to happen In order to convince the useMemo hook to run on every render you have to omit the dependency array Pass in only one argument the function Import useMemo hook from React import useEffect useMemo useState from react export default function App Create state for count const count setCount useState Create computationally expensive function const fibonacci num gt return num num fibonacci num fibonacci num Memoize fibonacci function const memoizedVal useMemo gt fibonacci count Above no dependency array is specified This will cause the useMemo to execute fibonacci function on every render Check if memoizedVal changes useEffect gt console log memoizedVal memoizedVal return lt div className App gt lt p gt count lt p gt lt button onClick gt setCount prevCount gt prevCount gt Increase count lt button gt lt div gt In the last example we removed the dependency array argument from the useMemo hook The useMemo hook now watches basically everything that happens When something happens that will cause re render useMemo will also execute the fibonacci function This will in turn change the memoizedVal This change will tell useEffect to execute the console log As a result a new value of memoizedVal will show up in the console To reiterate don t do this It doesn t make sense to use useMemo and then never let it memoize anything Use useMemo hook with cautionPerformance is important and it is easy to go over the edge when trying to optimizer everything It is just as easy to over use the React useMemo hook Think before you decide to use useMemo hook Remember that the hook itself introduces some overhead The hook brings in new complex logic you have to take into account It can also create new performance issues issue you didn t have before When you memoize something you store it in the memory This gives more space for the CPU However there are still resources that are consumed The only thing that changed is the type of resource it consumes So use useMemo only for really expensive computations Make sure you use that memory for things that can make a difference Use profiling tools to identify those expensive computations computations that use a lot of resources Try to optimize these with useMemo and see if the profile changes for the better Additional warning Don t rely on useMemo too much As is mentioned in the React docs useMemo doesn t guarantee you to execute the function only when dependencies change React may also choose to remove memoized values and recalculate them so it can free up memory So make sure your code works without useMemo as well One more thing Don t use functions you passed to useMemo hook to create side effects Side effects should be made inside the useEffect hook Also don t use useMemo to update state values This is also a side effect but it is important to mention it Use useMemo only for what it is intended to memoize output values Conclusion The React useMemo hook made simpleThe React useMemo hook can be useful when you look for ways to improve performance of your React applications It can help you optimize expensive computations by memoizing output of these computations and re run them only when necessary I hope that this tutorial helped you understand what the useMemo hook is how it works and also how to use it	2021-05-31
