In the slide show project, I reduced the size of javascript code for the same output.

<pre> <script>

let slideIndex = 1;


const slides = document.getElementsByClassName("mySlides");



function showSlides(n) {
if (n > slides.length) slideIndex = 1;
if (n < 1) slideIndex = slides.length;

for (let slide of slides) slide.style.display = "none";
slides[slideIndex - 1].style.display = "block";
}

function changeSlide(n) {
showSlides(slideIndex += n);
}

showSlides(slideIndex);


document.addEventListener("contextmenu", e => e.preventDefault());
document.onkeydown = e => {
if (
e.keyCode === 123 || // F12
(e.ctrlKey && e.shiftKey && (e.keyCode === 73 || e.keyCode === 74)) ||
(e.ctrlKey && e.keyCode === 85)
) {
return false;
}
}
</script> </pre>
