![]() ![]() However, that’s not a real truth, because if you want to use useContext and useReducer for complicating app, you should use several context and reducer so that your app or index.js could have a lot of “Provider” and that’s a little bit messy and confusing. ![]() So someone says we don’t need to have redux any more(Even my front-end developer said she avoid using redux currently). In other words, you should pass the state to achieve the destination even if almost all states don’t use this passed state.Īs you might know, modern react has several methods to pass your state like “useReducer”, “useContext”. When it comes to basic react in the past, you could pass the state just next to the state by using props.

Redux is an open-source JavaScript library for managing and centralizing application state. So, I would share my basic knowledge and how to create a basic counter app in this article, and I would share how to create a more complicating app in the next article. I decided to share my knowledge about redux dividing into 2parts, which are basic and real example because redux is a little bit confusing method. So how can you manage states of your app? Well, actually you have several ways, and the useful one is redux. Enable JavaScript to view data.If you want to create a more complicating app, you should add the feature of state management. min (end, len ) : len if (end 0 ) ( ) ) 規範 SpecificationĮCMAScript Language Specification # īCD tables only load in the browser with JavaScript enabled. ![]() max ( 0, len + start ) // Handle negative value for "end" var upTo = ( typeof end = 'number' ) ?
