How do I implement one-way data binding in my application?

One-way data binding means that data flows in one direction, from the model to the view. You can implement it using frameworks like React or Angular. Would you like a specific example?

Yes, can you show me an example using React?

Sure! In React, you can use state to manage your data. For example, you can create a component that displays a value from the state and updates it using an input field. Here's a simple code snippet:

import React, { useState } from 'react';

function App() {
  const [value, setValue] = useState('');

  return (
    <div>
      <input type='text' onChange={(e) => setValue(e.target.value)} />
      <p>{value}</p>
    </div>
  );
}

This way, the input updates the displayed value, demonstrating one-way data binding.

What if I want to implement it in Angular?

In Angular, you can use property binding to achieve one-way data binding. For example, you can bind a property of a component to a template. Here's a simple example:

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  template: `<input [(ngModel)]="name" /> <p>{{ name }}</p>`
})
export class AppComponent {
  name: string = '';
}

In this case, the input field updates the displayed name, showing one-way data binding.
