The html link (anchor tag) has an attribute that we can set called target="_blank", when we want to open hyperlinks on a new tab. If these links are links to external websites this can pose as performance and security threats.
rel='noopener' and rel='noreferrer' can help neutralize those threats.
when we open external site using target="_blank" attribute, that site has access to our window object via window.opener property. if that is a malicious website then you can image how that may pose an issue.
rel="noopener" prevents the new page from accessing the window.opener property and ensures it runs in a separate process.
rel="noreferrer" ensures more sticter privacy policies on your website. When we visit an external site that site can get information about where you came from, where were you refered from. The noreferrer property hides that information. This is useful when we dont want to expose our sites users information about what site they previously visited.
