RegEx Tutorial - A Tutorial on Regular Expressions and HTML Parsing

A Regular Expression is, in theoretical computer science, a special text string for defining a search pattern. This pattern is later used by string searching algorithms for "find" or "find and replace" operations on strings. In this RegEx tutorial, we walk through some RegEx examples, explore the power of JavaScript's RegEx implementation as well as its limitations, and examine why a given RegEx implementation may not be the best tool for parsing arbitrary HTML.

Watch this video to learn:

- What a Regular Expression is
- How RegEx is implemented in JavaScript
- The limits of RegEx when parsing HTML
