问题 So this is a little crazy. There's a web app that I use that is built with React, which has made certain design decisions that I disagree with. Luckily, the design is actually simple to change exactly the way I want. I can just open the Chrome React devtools and change the props assigned to a specific component. But I don't want to manually do this every time, that's not worth it. I want to write a (super hacky) personal bit of javascript that I can inject into the page, which modifies the

问题 What confused me is that both functional component and class based component can now use State and Props but in different implementations. I prefer class based component since I am angular developer and I find it more comfortable to work with these type of components. But I searched for this and many experts said it is better to use functional components as mush as possible. I want to know if it really matters with tech companies when someone apply for react developer position. Would they

问题 A React.js warning was thrown: IndexPage: It is not recommended to assign props directly to state because updates to props won't be reflected in state. In most cases, it is better to use props directly. I had the following code: class IndexPage extends React.Component<IProps, IState> { constructor(props) { super(props) this.state = props } } But, when I have changed my code to: class IndexPage extends React.Component<IProps, IState> { constructor(props) { super(props) this.state = {...props}

问题 I'm curious if passing setState as a prop to a child (dumb component) is violating any "best practices" or will affect optimization. Here is an example where I have the parent container passing state and setState to two child components, where the child components will call the setState function. I do not explicitly call setState in the children, they reference a service to handle the correct setting of state properties. export default function Dashboard() { const [state, setState] = useState

问题 I need a solution for radio buttons, but the options array which is the main array is outside the class component. In this case, I will get OPTIONS array items through props but not hardcoded. How is it possible for me to Pass props outside class component Make OPTIONS state object and then pass it to checkboxes, which is inside state. import React, { Component } from "react"; import Checkbox from "./Checkbox"; const OPTIONS = ["One", "Two", "Three"]; class App extends Component { state = {
