How to use the markdown-it/lib/common/html_blocks.join function in markdown-it

const blockNames = require('markdown-it/lib/common/html_blocks')
const HTML_OPEN_CLOSE_TAG_RE = require('markdown-it/lib/common/html_re').HTML_OPEN_CLOSE_TAG_RE

// An array of opening and corresponding closing sequences for html tags,
// last argument defines whether it can terminate a paragraph or not
const HTML_SEQUENCES = [
  [/^<(script|pre|style)(?=(\s|>|$))/i, /<\/(script|pre|style)>/i, true],
  [/^/, true],
  [/^<\?/, /\?>/, true],
  [/^/, true],
  [/^/, true],
  // PascalCase Components
  [/^<[A-Z]/, />/, true],
  // custom elements with hyphens
  [/^<\w+\-/, />/, true],
  [new RegExp('^|$))', 'i'), /^$/, true],
  [new RegExp(HTML_OPEN_CLOSE_TAG_RE.source + '\\s*$'), /^$/, false]
]

module.exports = md => {
  md.block.ruler.at('html_block', htmlBlock)
}

function htmlBlock (state, startLine, endLine, silent) {
  let i, nextLine, lineText
  let pos = state.bMarks[startLine] + state.tShift[startLine]
  let max = state.eMarks[startLine]

  // if it's indented more than 3 spaces, it should be a code block
  if (state.sCount[startLine] - state.blkIndent >= 4) { return false }

  if (!state.md.options.html) { return false }
