Pardon me if this is a ridiculous question. But can props be forged in React? In other words can someone navigating your website find a way to deliberately change the values of the props that are being passed from component to component in a manipulative way to bypass the natural flow of your website?

In React, props (short for properties) are immutable. This means that once props are passed from a parent component to a child component, they cannot be changed by the child component. This prevents direct manipulation of props within a component.
However, if a component needs to modify the data it receives via props, it typically does so by informing its parent component to update the props via callbacks or state management techniques like Redux or React’s built-in state management.
That said, if you’re concerned about data integrity or security, it’s essential to validate and sanitize data both on the client side (using React) and on the server side. Never trust data that comes from the client side, always validate it on the server side to ensure that your application remains secure and robust.
No you cant change the props in react. But yes you can provide callbacks, or make use of context APIs, redux, localstorage, etc to let your parent component know the updated value!!
No, in React, props (short for properties) are values passed from a parent component to a child component. They are immutable and cannot be changed or forged within the child component. The child component receives props and uses them to render its output based on the provided data.
If you need to modify data or manage state within a component, you would typically use state in a class component or the useState hook in a functional component. Props, on the other hand, are intended for one-way communication from parent to child.
