I agree with siraj, strictly speaking the example in the accepted answer is not a true HOC. The distinguishing feature of a HOC is that it returns a component, whereas the PrivateRoute component in the accepted answer is a component itself. So while it accomplishes what it set out to do just fine, I don’t … Read more
In my opinion, this is a completely unnecessary feature in TypeScript. To disable it, you need to change the file tsconfig.json: “compilerOptions”: { // … “noPropertyAccessFromIndexSignature”: false, // … }
Since your condition is falsy and so doesn’t return the second argument (<GeneralLoader />), it will return profileTypesLoading, which is a number, so react will render it because React skips rendering for anything that is typeof boolean or undefined and will render anything that is typeof string or number: To make it safe, you can … Read more
You can change the null value to undefined to use the default value. <Component bedrooms={bedrooms || undefined} />
You can export multiple functions from a file, no React needed per se: Helpers.js: export function plus(a, b) { return a + b; } export function minus(a, b) { return a – b; } export function multiply(a, b) { return a * b; } export function divide(a, b) { return a / b; } You … Read more
React’s one-way data-binding model means that child components cannot send back values to parent components unless explicitly allowed to do so. The React way of doing this is to pass down a callback to the child component (see Facebook’s “Forms” guide). class Parent extends Component { constructor() { this.state = { value: ” }; } … Read more
Vue sets all the properties in the data option to setters/getters to make them reactive. See Reactivity in depth Since you want myArray to be static you can create it as a custom option which can be accessed using vm.$options export default{ data() { return{ someReactiveData: [1, 2, 3] } }, //custom option name myArray … Read more
A simplified solution using state could look like this: class Typing extends React.Component { constructor(props) { super(props); this.state = { disabled: false } } handleGameClik() { this.setState( {disabled: !this.state.disabled} ) } render() { return( <div> <input className = “typing-container” placeholder= ” type here ” disabled = {(this.state.disabled)? “disabled” : “”}/> <button onClick = {this.handleGameClik.bind(this)}> Start … Read more
This is not possible the-angular-way anymore since the replace: true flag has been deprecated Why is replace deprecated in AngularJS? the replace: true flag had come up with more problems than solutions which is why it was removed. therefore you can not build directives in such a way anymore and provide valid table-tr-td markup. However, … Read more
They were most likely looking for examples of web frameworks – for example, JSF is a component-based framework, and Struts is a request-based framework. Request-based frameworks generally make it clear through their APIs that they’re working with parsing an HTML request / generating an HTML response, while Component-based frameworks attempt to abstract this away and … Read more
