html button won't open link in a new window/tab when using window.location

FYI:  JavaScript uses different terms & syntax. For details, see below.

Adding to @r_tist's reply, the code would look like

<a href="https://google.com" class="btn btn-outline-primary btn-lg mt-4" target="_blank">Request Sample</a>

This code is semantically more correct than using a button element because of the following statements:

• Links take the user to a new location, such as a new web page or new section of the current page. 
• Buttons trigger some action, such as showing content on the page that was previously hidden, playing a video, or submitting a form.

Are you using Bootstrap? With all of those button classes, why not just change the button --> a and just have a stylized link that looks like a button? Then you can remove the javascript and use a href value.
