when I open inspect element I see syntaxError under console tab?

hello.

I get this syntaxError under console tab when I open inspect element on my homepage .

Uncaught SyntaxError: Unexpected token

I have deleted every unneccesary scripts but the problem exists.

I have only this 2 scripts.

the first is for FAQ . I don’t know if something wil be wrong here!

	<script> 
var acc = document.getElementsByClassName('accordion');
var len = acc.length;
for (var i = 0; i < len; i++) {
  acc[i].addEventListener('click', event => {
    const accordion = event.currentTarget;
    const currentlyActiveAccordion = document.querySelector('.accordion.active');
    if (currentlyActiveAccordion && currentlyActiveAccordion !== accordion) {
      currentlyActiveAccordion.classList.toggle('active');
      currentlyActiveAccordion.nextElementSibling.style.maxHeight = 0;
    }
    accordion.classList.toggle('active');
    var panel = accordion.nextElementSibling;
    if (panel.style.maxHeight) {
      panel.style.maxHeight = null;
    } else {
      panel.style.maxHeight = panel.scrollHeight + 'px'
    }
  });>
}
	</script>

and second is for slider show :

<script>


    let slideIndex = 0;
      showSlides();

      function showSlides() {
        let i;
        let slides = document.getElementsByClassName("mySlides");
        let dots = document.getElementsByClassName("dot");		  
       
        for (i = 0; i < slides.length; i++) {
          slides[i].style.display = "none";
        }
        slideIndex++;
        if (slideIndex > slides.length) {
          slideIndex = 1;
        }
        for (i = 0; i < dots.length; i++) {
          dots[i].className = dots[i].className.replace(" active", "");
        }
        slides[slideIndex - 1].style.display = "block";
        dots[slideIndex - 1].className += " active";
        setTimeout(showSlides, 4000); // 4000 = Change image every 4 seconds
      }


</script>





	   

may be it can be in this slidershow script something wrong! but I don’t see myself anything.

can some one tell me what it can be this syntaxError?

thanks
