Welcome to RegExpress, a tool that lets you build Javascript regular expressions by creating a syntax diagram instead of having to memorize countless esoteric symbols.
RegExpress will show you the text and the "regex railroad" syntax diagram for any regular expression. Type in a regex to see the diagram it creates, or build your own out of the library components.
Each library component represents a type of character or group of characters. Together, these components will describe a pattern when read left to right on the railroad. This pattern is just another way to describe a regular expression.
