Calling Parent Methods in ReactJS: Essential JavaScript Tips

In ReactJS, it is common to have child components that need to communicate with their parent components. One way to achieve this is by calling a method defined in the parent component from the child component.

To call a parent method in ReactJS, you can pass the method as a prop to the child component. Then, the child component can call the method using the props passed down from the parent.

Here is an example of how to call a parent method in ReactJS:


class ParentComponent extends React.Component {
parentMethod() {
console.log("Parent method called");
}

render() {
return (

Call parent method

);
}
}


In this example, the ParentComponent defines a method called parentMethod(). The method is passed as a prop to the ChildComponent using the prop name parentMethod.

The ChildComponent defines a handleClick() method that calls the parentMethod() using the props passed down from the parent. The handleClick() method is called when the button is clicked.

By passing a method as a prop, you can easily call parent methods from child components in ReactJS. This is a useful technique for building complex user interfaces with ReactJS.
