JC's Regex Tutorial

Regex is short for regular expression, and you may also see some people use RE to refer to that as well. This is a concept in computer science. By using this rule you can match the string. So that Regular expressions are often used to match, retrieve, and replace text that matches a pattern.

Summary

We will talk about the basic Regex components next. Hopefully you will understand /^([a-z0-9_\.-]+)@([\da-z\.-]+)\.([a-z\.]{2,6})$/ after reading this tutorial. Just a reminder; if you want to use Regex in JavaScript, add / before Regex without space and add another / after Regex without space to let JS know you want to get string only.

This guide was created to help myself and you learn more about regular expressions and how to use them. Regular expressions are special characters that define a search pattern.

Summary

The regular expression, or regex for short, below is a search pattern for matching a Url. Since this regular expression is between two slashes it is called a regular expression literal. It is made up of anchors, grouping constructions, bracket expressions, and quantifiers. We will look at each component of the regular expression so they make more sense.
/^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$/
