How to pass a parameter to an event handler or callback?

You can use an arrow function to wrap around an event handler and pass parameters:

<button onClick={() => this.handleClick(id)} />

This is an equivalent to calling .bind:

<button onClick={this.handleClick.bind(this, id)} />

Apart from these two approaches, you can also pass arguments to a function which is defined as arrow function

<button onClick={this.handleClick(id)} />;
handleClick = (id) => () => {
console.log('Hello, your ticket number is', id);
