How do I add custom JS to react

Question

Can you tell me how do I add custom JS to react? Use code snippets of good examples to explain it.

Answer 1

Creating custom objects in React involves defining JavaScript classes or functions that encapsulate specific behaviors and properties. Here's how you can create and utilize custom objects within your React application:

1. Define a JavaScript Class:

You can define a custom object using a JavaScript class.

class Card {

  constructor(rank, suit) {

    this.rank = rank;

    this.suit = suit;

  }

  display() {

    return `${this.rank} of ${this.suit}`;

  }

}

In this example, the Card class has a constructor that initializes the rank and suit properties and a display method to return a string representation of the card.

2. Create an Instance of the Class:

To use this class in your React component, create an instance of Card.

const myCard = new Card('Ace', 'Spades');

console.log(myCard.display()); // Outputs: Ace of Spades

3. Utilize the Custom Object in a React Component:

You can now use this custom object within your React components.

import React from 'react';

class Card {

  constructor(rank, suit) {

    this.rank = rank;

    this.suit = suit;

  }

  display() {

    return `${this.rank} of ${this.suit}`;

  }

}

const CardComponent = () => {

  const myCard = new Card('King', 'Hearts');

  return (

    <div>

      <h1>Card Details</h1>

      <p>{myCard.display()}</p>

    </div>

  );

};

export default CardComponent;
