Parsing Error

Here is my code. I have named all elements properly. At line 20, it gives an error:

Parsing error: unexpected character ’ ’

How can I resolve this? Thanks

import wixAnimations from 'wix-animations';

const ACTIVE_COLOR = '#EF8940';
const DEFUALT_COLOR = '#324655';

function initFAQrepeater() {
    $w('#FAQrepeater').forEachItem(($item, itemData, index) => {
        $item('#Qbutton').onClick((event) => {
           console.log(event);
            openRelevantContent(index);
        })
    })
}

function openRelevantContent(targetIndex) {
   $w('#FAQrepeater').forEachItem(($item, itemData, index) =>{
      const contentBox = $item('#FAQcontent');
        const button = $item('#Qbutton');
        const arrow = $item('#FAQarrow');​
        if (targetIndex === index) {
            contentBox.collapsed ?
                expandFAQcontent(contentBox, button, arrow) :
                collapseFAQcontent(contentBox, button, arrow);
        } else {
            collapseFAQcontent(contentBox, button, arrow);
        }
   })
}

function expandFAQcontent(contentBox, button, arrow) {
    contentBox.expand();
    button.style.color = ACTIVE_COLOR;
    wixAnimations.timeline()
        .add(arrow, { rotate: 180, duration: 300 })
        .play();
}​
function collapseFAQcontent(contentBox, button, arrow) {
    contentBox.collapse();
    button.style.color = DEFUALT_COLOR;
    wixAnimations.timeline()
        .add(arrow, { rotate: 0, duration: 300 })
        .play();
}​
export function FAQdataset_ready() {
    initFAQrepeater();
}
