# Regex String Manipulator

### Intro

A regular expression (shortened as regex) is a sequence of characters that specifies a search pattern. A common use for regex is to match strings or parts of strings in order to do something with the result. For example, the default expression of `a+` will return all instances of the letters **a** found within the input string. So the string `Cavarly` would output `aa`  because the word C**`a`**v**`a`**lry has two `a`s.

### UI

**Regex** - enter your regular expression.

Examples:

| String                 | Regex     | Result         |
| ---------------------- | --------- | -------------- |
| Hello World.           | `\s`      | HelloWorld.    |
| As Capably as Cavalry. | `C.....y` | CapablyCavalry |
| Is it Colour or Color? | `Colou?r` | ColourColor    |
| 3 is the magic number. | `\d`      | 3              |
