RegExp

Methods

(static) isRegExp(value) → {boolean}

Returns whether the given value is a regexp, regardless of which context it comes from. The context may be another frame. This is the proper idiomatic way to test whether an object is a regexp and replaces the less generally useful `instanceof` check (which does not work across contexts) and the strangeness that the `typeof` a regexp is `"object"`.
Parameters:
Name Type Description
value any value
Source:
Returns:
whether the given value is a regexp
Type
boolean
