The History of HTML5

Regular Expressions are a powerful tool in the arsenal of any programmer, yet they just might not stumble on them before they have written a lot of code to do their own string processing. Make sure your team knows about regular expressions and further, make sure they know how to use them. This object is incredibly useful and can help you with most any data parsing and matching. You can easily validate data, find words, find word fragments, or maybe just remove html tags from your string. Whatever the reason, you will do yourself, your team, and your business a favor if you will make it one of the core technologies they know.
