Code snippets without syntax highlighting are unsightly. No one wants to view these code snippets. They are extremely hard to read and deeply unstylistic.

A project called PrismJS for syntax highlighting
Another project succinctly named prism-react-renderer enables us to manipulate the PrismJS syntax highlighted output as well as add extraneous react components into the code blocks. Subsequently, a theme object can be passed as a prop to further control the syntax highlighting.
