-Type: `Function`

-A function to highlight code blocks. The function takes three arguments: code,
-lang, and callback. The above example uses async highlighting with
-[node-pygmentize-bundled][pygmentize], and here is a synchronous example using
-[highlight.js][highlight] which doesn't require the callback argument:
-
-```js
-marked.setOptions({
-  highlight: function(code, lang) {
