i have 2 svgs and i added a mouseover event but i feel like my code is repetitve if iam right is there is any way to make it more minimal ?
const previousBtn = document.querySelector('.previous');
const nextBtn = document.querySelector('.next');
// Previous Button hover
previousBtn.addEventListener('mouseover', ()=>{
const previousCircle = document.querySelector('.previous-circle svg');
const leftArrow = document.querySelector('.previous-arrow svg');
previousCircle.style.transform = 'translateX(-10px)';
previousCircle.style.transition = '0.5s';
leftArrow.style.transform = 'translateX(-20px)';
leftArrow.style.transition = '0.5s';
});
previousBtn.addEventListener('mouseleave', ()=>{
const previousCircle = document.querySelector('.previous-circle svg');
const previousArrow = document.querySelector('.previous-arrow svg');
previousCircle.style.transform = 'none';
previousCircle.style.transition = '0.5s';
previousArrow.style.transform = 'none';
previousArrow.style.transition = '0.5s';
});
// Next button hover
nextBtn.addEventListener('mouseover', ()=>{
const nextCircle = document.querySelector('.next-circle svg');
const nextArrow = document.querySelector('.next-arrow svg');
nextCircle.style.transform = 'translateX(10px)';
nextCircle.style.transition = '0.5s';
nextArrow.style.transform = 'translateX(20px)';
nextArrow.style.transition = '0.5s';
});
nextBtn.addEventListener('mouseleave', ()=>{
const nextCircle = document.querySelector('.next-circle svg');
const nextArrow = document.querySelector('.next-arrow svg');
nextCircle.style.transform = 'none';
nextCircle.style.transition = '0.5s';
nextArrow.style.transform = 'none';
nextArrow.style.transition = '0.5s';
});

231,269 PointsFunctions are often good for compacting repetitive code:
const previousBtn = document.querySelector('.previous');
const nextBtn = document.querySelector('.next');
function addHoverEvent(element, event, circle, arrow, cxform, axform) {
element.addEventListener(event, ()=>{
const theCircle = document.querySelector(circle);
const theArrow = document.querySelector(arrow);
theCircle.style.transform = cxform;
theCircle.style.transition = '0.5s';
theArrow.style.transform = axform;
theArrow.style.transition = '0.5s';
});
}
// Previous Button hover
addHoverEvent(previousBtn, 'mouseover', '.previous-circle svg', '.previous-arrow svg',
'translateX(-10px)', 'translateX(-20px)');
addHoverEvent(previousBtn, 'mouseleave', '.previous-circle svg', '.previous-arrow svg',
'none', 'none');
// Next button hover
addHoverEvent(nextBtn, 'mouseover', '.next-circle svg', '.next-arrow svg',
'translateX(-10px)', 'translateX(-20px)');
addHoverEvent(nextBtn, 'mouseleave', '.next-circle svg', '.next-arrow svg',
'none', 'none');

231,269 PointsAlways happy to help. And it really wasn't so bad, I just took one of your calls, wrapped it in the new function, and made it generic by converting anything that differed between the repeated code elements into a parameter. The fact that your code was very clear and clean to start with was very helpful!
Happy coding!
