RegExp.prototype.compile()

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The deprecated compile() method is used to (re-)compile a regular expression during execution of a script. It is basically the same as the RegExp() constructor.

The compile() method is deprecated and is only specified for compatibility reasons. You can just use the RegExp() constructor to achieve the same effect.
