Can be called without `new`.\n *\n * ##### presetName\n *\n * MarkdownIt provides named presets as a convenience to quickly\n * enable/disable active syntax rules and options for common use cases.\n *\n * - [\"commonmark\"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/commonmark.js) -\n * configures parser to strict [CommonMark](http://commonmark.org/) mode.\n * - [default](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/default.js) -\n * similar to GFM, used when no preset name given. Enables all available rules,\n * but still without html, typographer & autolinker.\n * - [\"zero\"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/zero.js) -\n * all rules disabled. Useful to quickly setup your config via `.enable()`.\n * For example, when you need only `bold` and `italic` markup and nothing else.\n *\n * ##### options:\n *\n * - __html__ - `false`. Set `true` to enable HTML tags in source. Be careful!\n * That's not safe! You may need external sanitizer to protect output from XSS.\n * It's better to extend features via plugins, instead of enabling HTML.\n * - __xhtmlOut__ - `false`. Set `true` to add '/' when closing single tags\n * (`
`). This is needed only for full CommonMark compatibility. In real\n * world you will need HTML output.\n * - __breaks__ - `false`. Set `true` to convert `\\n` in paragraphs into `
`.\n * - __langPrefix__ - `language-`. CSS language class prefix for fenced blocks.\n * Can be useful for external highlighters.\n * - __linkify__ - `false`. Set `true` to autoconvert URL-like text to links.\n * - __typographer__ - `false`. Set `true` to enable [some language-neutral\n * replacement](https://github.com/markdown-it/markdown-it/blob/master/lib/rules_core/replacements.js) +\n * quotes beautification (smartquotes).\n * - __quotes__ - `“”‘’`, String or Array. Double + single quotes replacement\n * pairs, when typographer enabled and smartquotes on. For example, you can\n * use `'«»„“'` for Russian, `'„“‚‘'` for German, and\n * `['«\\xA0', '\\xA0»', '‹\\xA0', '\\xA0›']` for French (including nbsp).\n * - __highlight__ - `null`. Highlighter function for fenced code blocks.\n * Highlighter `function (str, lang)` should return escaped HTML. It can also\n * return empty string if the source was not changed and should be escaped\n * externaly. If result starts with `):\n *\n * ```javascript\n * var hljs = require('highlight.js') // https://highlightjs.org/\n *\n * // Actual default values\n * var md = require('markdown-it')({\n * highlight: function (str, lang) {\n * if (lang && hljs.getLanguage(lang)) {\n * try {\n * return '' +\n * hljs.highlight(lang, str, true).value +\n * '
