# is-regexp > Check if a value is a regular expression ## Why not just use instanceof instead of this package? > instanceof does not work correctly for all types and it does not work across [realms](https://stackoverflow.com/questions/49832187/how-to-understand-js-realms/49832343#49832343). Examples of realms are iframes, windows, web workers, and the vm module in Node.js.
