<div class="carousel">
  <div class="carousel-wrapper">
    <div class="carousel-item">Item 1</div>
    <div class="carousel-item">Item 2</div>
    <div class="carousel-item">Item 3</div>
  </div>
  <button class="carousel-prev">Prev</button>
  <button class="carousel-next">Next</button>
</div>

<style>
.carousel {
  position: relative;
  width: 100%;
  height: 200px;
  overflow: hidden;
}

.carousel-wrapper {
  position: absolute;
  width: 300%;
  height: 100%;
  display: flex;
  transition: transform 0.5s ease;
}

.carousel-item {
  flex: 1;
  display: flex;
  justify-content: center;
  align-items: center;
  font-size: 3em;
}

.carousel-prev,
.carousel-next {
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
  width: 50px;
  height: 50px;
  border: none;
  background-color: #fff;
  cursor: pointer;
}

.carousel-prev {
  left: 0;
}

.carousel-next {
  right: 0;
}
</style>

<script>
const carousel = document.querySelector('.carousel');
const wrapper = carousel.querySelector('.carousel-wrapper');
const prevButton = carousel.querySelector('.carousel-prev');
const nextButton = carousel.querySelector('.carousel-next');
const items = carousel.querySelectorAll('.carousel-item');
const itemWidth = items[0].offsetWidth;

let currentPosition = 0;

function slideTo(position) {
  if (position > 0 || position < -(items.length - 1) * itemWidth) {
    return;
  }

  currentPosition = position;
  wrapper.style.transform = `translateX(${position}px)`;
}

prevButton.addEventListener('click', () => slideTo(currentPosition + itemWidth));
nextButton.addEventListener('click', () => slideTo(currentPosition - itemWidth));
</script>

You should give more information in your request of at least showing SOME SORT of effort in learning or people wont be inclined to help you out bud.

you can simply be googling and get the answers from google itself.

one solution as follows…

// Variables
let prev = document.querySelector('.prev');
let next = document.querySelector('.next');
let imgs = document.querySelectorAll('.carousel-img');
let dots = document.querySelectorAll('.dot');
let captions = document.querySelectorAll('.carousel-caption')
let totalImgs = imgs.length;
let imgPosition = 0;

// Event Listeners
next.addEventListener('click', nextImg);
prev.addEventListener('click', prevImg);

// Update Position
function updatePosition (){
//   Images
  for(let img of imgs){
    img.classList.remove('visible');
    img.classList.add('hidden');
  }
  imgs[imgPosition].classList.remove('hidden');
  imgs[imgPosition].classList.add('visible')
//   Dots
  for (let dot of dots) {
     dot.className = dot.className.replace(" active", "");
  }
    dots[imgPosition].classList.add('active');
//   Captions
  for (let caption of captions) {
      caption.classList.remove('visible');
      caption.classList.add('hidden');
  }
    captions[imgPosition].classList.remove('hidden');
    captions[imgPosition].classList.add('visible')
}

// Next Img
function nextImg(){
  if (imgPosition === totalImgs -1){
        imgPosition = 0;
    } else{
        imgPosition++;
    }
    updatePosition();
}
//Previous Image
function prevImg(){
  if (imgPosition === 0){
        imgPosition = totalImgs-1;
    } else{
        imgPosition--;
    }
    updatePosition();
}

// Dot Position
dots.forEach((dot, dotPosition) => {
  dot.addEventListener("click", () => {
    imgPosition = dotPosition
    updatePosition(dotPosition)
  })
})
