Last release: 12/12/2024

is-regex is a JavaScript module that checks whether a given value is a JS regular expression, including cases that work across realms and iframes. It can be useful in validation logic where you need to distinguish regex objects from other values, for example returning true for /a/g and new RegExp('a','g').
