Performance is certainly a big problem in how the DOM is manipulated on the page, but the clever Reactjs realizes the virtual Dom technology, which is one of his highlights.

IntroducedThe purpose of 1,react JS is to make the V layer of the front end more modular and better reusable, it can use simple HTML tags to create more custom component tags, internal binding events, but also let you free from the operation of the DOM, only need to manipulate the data will change the corresponding DOM.The purpose of 2,react native is that we can use the front-end technology stack to create a framework that can run on different platforms. You can create apps that run on the mobi

I'm going to use Reactjs to do the V-level work and laravel to do the C and M work. Is this method feasible? Is there any need for this? In addition, for example login, how blade should be translated into Reactjs's component code, or how can I replace Laravel's front-end template with Reactjs: Are there any related project codes that can be referenced by wood?

Make a Mobile App with Reactjs in Minutes Ken Wheeler (@ken_wheeler) React allows front-end developers to build their apps in an unprecedented way.

. X is not that good.React Features: Advantages:The great thing about 1.React is that it puts forward the novel idea of virtual DOM, and this idea derives from react Native, which is likely to unify web/native development. On the performance side, because of the virtual DOM technique, Reactjs only updates the DOM when calling SetState, and updates the virtual DOM first, then compares the actual DOM with the actual DOM. This process compared to the Ang

seems like everything is fine, but the problem is that the parent and child components are used to refer to the same object, and when the user triggers the Click event, the prop of Innercomponent will change, so its function will be shouldComponentUpdate called, and if you follow our current shouldComponentUpdate than the logical words, this.props.value.foo and nextProps.value.foo are equal, because in fact, they both refer to the same object Oh ~ So, we will see that the Innercomponent UI is n
