Scrape anime info from MAL

scrapper.js

const h2 = document.querySelectorAll("h2");
const infoH2 = (() => {
    for (let i = 0; i < h2.length; i++) {
        if (h2[i].innerText === "Information") return h2[i];
    }
})();
// holds the elements between the Information (H2) and the next H2
const elList = [];
// start from the element after the H2
let now = infoH2.nextElementSibling;
do {
    elList.push(now);
    now = now.nextElementSibling;
} while (now.tagName !== "H2");
// Rough Serialization
const kvmap = elList.map((el) => {
    try {
        return {
            key: el.getElementsByTagName("span")[0].innerText,
            value: el.innerText
        };
    } catch (e) {
        return null;
    }
});
const cleanedObj = kvmap.reduce((acc, val) => {
    if (val) {
        // key contains a extra `:`. val contains the text contents
        // of key plus the value. ex: Status:: "Status: Finished Airing",
        // which we gotta clean up.
        acc[val.key.slice(0, -1)] = val.value.slice(val.key.length + 1);
    }
    return acc;
}, {});
