--description--

Given a string that includes a blockquote in Markdown, return the equivalent HTML string.

A blockquote in Markdown is any line that:

  • Starts with zero or more spaces
  • Followed by a greater-than sign (>)
  • Then, one or more spaces
  • And finally, the blockquote text.

Return the blockquote text surrounded by opening and closing HTML blockquote tags.

For example, given "> This is a quote", return <blockquote>This is a quote</blockquote>.

Note: The console may not display HTML tags in strings when logging messages. Check the browser console to see logs with tags included.

--hints--

parseBlockquote("> This is a quote") should return "<blockquote>This is a quote</blockquote>".

js
assert.equal(parseBlockquote("> This is a quote"), "<blockquote>This is a quote</blockquote>");

parseBlockquote(" > This is also a quote") should return "<blockquote>This is also a quote</blockquote>".

js
assert.equal(parseBlockquote(" > This is also a quote"), "<blockquote>This is also a quote</blockquote>");

parseBlockquote(" > So Is This") should return "<blockquote>So Is This</blockquote>".

js
assert.equal(parseBlockquote("  >    So  Is  This"), "<blockquote>So  Is  This</blockquote>");
