Has anyone passed the optional bonus for the markdown previewer

Has anyone passed the optional bonus for the markdown previewer


The goal I am referring to is

Optional Bonus (you do not need to make this test pass): When I click a link rendered by my markdown previewer, the link is opened up in a new tab (HINT: read the Marked.js docs for this one!).

I have looked on the forum and one of the first responses to a similar question suggests to skip it since there is no relevant info in the DOCS in marked.js
Is this true? Should this optional bonus be skipped?
I tried implementing the code below but could not get it to execute properly. I found this code in a discussion in a GitHub thread about this issue.

const renderer = new marked.Renderer();
renderer.link = function( href, title, text ) {
  return '<a target="_blank" href="'+ href +'" title="' + title + '">' + text + '</a>';


The code did work for me just make sure to put the argument with the object and renderer property

const renderer = new marked.Renderer();

renderer.link = (address = "#", title = "", content = "") => (
   `<a target="_blank" href=${address} title=${title}>${content}</a>`
// then
marked(Your contend, { renderer }));

my code pen


I read the docs but didn’t fully understand them. I got the tests to pass by adding the target="_blank" after the fact, using the following function as part of my ‘handleChange’ function:

const addTarget = () => {
  const links = document.getElementById('preview').querySelectorAll('a');  
  links.forEach(l => l.setAttribute("target", "_blank"));


Wow, thanks I did not do the last line. If you dont mind, can you explain what the last line of your code is doing?

The line I am talking about is

marked(Your contend, { renderer }));


creative and simple. I like it!


My bad, I am not good on the explaining part. on the last line I am parsing the markup string with the marked plugin

if you parse with pure javascript

document.getElementById('my element').innerHTML = marked('markup string', { renderer })

If its React it would be

const Your_render_ function = (props)  {
  return (
           dangerouslySetInnerHTML={marked("your markup string", {  renderer })}>

In my case I used the html-react-parser instead of the dangerouslySetInnerHTML, in ordet to sanitize the markup.


Nice work, with few lines of code really simple, you got it to pass.
