Using `[removed].hash.includes` throws “Object doesn't support property or method 'includes'” in IE11

Question

I am checking the URL to see if it contains or includes a ? in it to control the hash pop state in the window. All other browsers aren’t having an issue, only IE.

Answer 1

According to the MDN reference page, includes is not supported on Internet Explorer. The simplest alternative is to use indexOf, like this:

if(window.location.hash.indexOf("?") >= 0) {
    ...
}
