Handling Events in React.js: An overview and examples

<p>In React, event management closely aligns with traditional HTML practices, with a key distinction being the naming of events. React follows a camelCase naming convention as opposed to the all-lowercase convention in HTML. For instance, the HTML onclick event becomes onClick in the React environment.</p> <p><img alt="" src="https://miro.medium.com/v2/resize:fit:540/1*vwDYI4v5L-4aaQ6_5TJ4QQ.gif" style="height:244px; width:600px" /></p> <p>To manage events in React, you can assign a function as a prop to the component responsible for triggering the event.&nbsp;When the event occurs, React automatically invokes the specified function, passing an event object as a parameter.&nbsp;This function can then access the event data and update the component&rsquo;s state, leading to a re-render of the user interface.</p> <p>Here&rsquo;s an example of how to handle a click event in React:</p> <p><img alt="" src="https://miro.medium.com/v2/resize:fit:630/1*sq0669r-ndVxJGwANtI1gg.png" style="height:176px; width:700px" /></p> <p>In the example above, we define a Button component that has a count state and a handleClick function that updates the state when the button is clicked. We pass the handleClick function as a prop to the button element using the onClick attribute. The button&rsquo;s label displays the current count value.</p> <p><a href="https://medium.com/@fardakarimov/handling-events-in-react-js-an-overview-and-examples-f7e2b059a53">Read More</a></p>
