Parser

A parser turns its input (often text in form of a file) into a more advantageous representation (usually a certain data structure in memory) to perform a specific task.

Common examples include:

https://github.com/BansheeTech/AgnosticHTML

AgnosticHTML: A utility function that safely parses HTML strings into DOM nodes, avoiding the use of innerHTML for security reasons.
