To make your SwiperJS slider more interactive and user-friendly in React, you can add navigation arrows and pagination bullets. These features help users move between slides easily and see their current position within the slider. SwiperJS provides built-in modules for both navigation and pagination, which you can enable and customize through the slider's props.

To enable navigation arrows, you use the navigation prop. This adds next and previous arrow buttons to your slider. For pagination bullets, you use the pagination prop. This displays clickable dots at the bottom of the slider, each representing a slide. You can also customize how these controls look and behave by passing options to these props.

For example, you can make pagination bullets clickable by setting clickable: true, or you can change their appearance with custom CSS. Similarly, navigation arrows can be styled or placed outside the slider if you want more control over their layout.

Here is a simple example of a SwiperJS slider in React with both navigation arrows and pagination bullets enabled and customized:

import { Swiper, SwiperSlide } from 'swiper/react';
import { Navigation, Pagination } from 'swiper/modules';
import 'swiper/css';
import 'swiper/css/navigation';
import 'swiper/css/pagination';

export default function MySlider() {
  return (
    <Swiper
      modules={[Navigation, Pagination]}
      navigation
      pagination={{ clickable: true }}
      spaceBetween={30}
      slidesPerView={1}
    >
      <SwiperSlide>Slide 1</SwiperSlide>
      <SwiperSlide>Slide 2</SwiperSlide>
      <SwiperSlide>Slide 3</SwiperSlide>
    </Swiper>
  );
}

In this example, the modules prop includes both Navigation and Pagination. The navigation prop enables the arrow buttons, and the pagination prop enables clickable bullets. You can further customize these controls by passing additional options or by overriding their styles in your CSS.
