Regular expressions are a tool, and a powerful one.
But like all tools, they need to be used in the right place, and the right way or they cause more problems than they solve.

A hammer is a powerful tool - but for some jobs a screwdriver is better. And instead of screwdriver, a spanner undoes bolts better. And the right size spanner won't round off the bolt so you can't use it again.

That's a Regex. It's a hammer / screwdriver / spanner thing that does what it is designed for extremely well: processing text strings to extract patterns. Misuse it to try and get it to count things, or order months, or - gawd forbid - process HTML and it will bite you very hard indeed.

The syntax is arcane, they are pretty slow to execute1, and the match strings can be hard to understand. But in the right place, at the right time? they can save you hours of work! Get a helper app and it can make them a load easier to work with2.


1 Counting Lines in a String[^] shows the difference.
2 I use Expresso[^] - it's free, and it examines and generates Regular expressions.
