>   The following are now properties of RegExp instances, no longer of the RegExp object.

>   Property | Description

> - RegExp Methods
>   The compile method is deprecated.

> - Escape sequences
>   Octal escape sequences (\ followed by one, two, or three octal digits) are deprecated in string and regular expression literals.
>   The escape and unescape functions are deprecated. Use encodeURI, encodeURIComponent, decodeURI or decodeURIComponent to encode and decode escape sequences for special characters.
