Lightweight, robust, elegant syntax highlighting

 A spin-off project from Dabblet. Some of its unique features include:
  * It’s tiny. The core is only 1.5KB minified & gzipped.
  * It’s incredibly extensible. Not only it’s easy to add new languages, but
    also to extend existing ones.
  * It encourages good author practices. Other highlighters encourage or even
    force you to use elements that are semantically wrong, like <pre> (on its
    own) or <script>. Prism forces you to use the only semantically correct
    element for marking up code: <code>.
  * One of its best features: The language definition is inherited. This means
    that if multiple code snippets have the same language, you can just define
    it once, in one of their common ancestors.
  * It looks good. All three of its existing themes.
  * It supports parallelism through Web Workers, for better performance in
    certain cases.
  * It doesn’t force you to use any Prism-specific markup, not even a
    Prism-specific class name, only standard markup you should be using anyway.
