    return `<${type}${attr}>${children.join('')}</${type}>`;

Here children.join("") should not generate , between the elements, unless the children array contains arrays inside itself. That might happen, we need to find a test case for it. If that's the case we might need some recursive function for handling those cases.

Wrote a recursive flattening function which fixes the problem:

const flatten = arr =>
    Array.isArray(arr)
        ? arr.map(flatten).join('')
        : arr;
