How do I make a web page show up only once?

Question

I have made a HTML and CSS page which showcases the features of my web app. Now I want this page to load only for new visitors. If a returning visitors vists my domain, it should redirect him/her to the web platform.

Essentially, the new user should see "Landing Page" while a returning user should be redirected to "Web Platform"

I would prefer to do it using direct javascript into my index.html file if possible. I am assuming that LocalStorage can help out here. But I am honestly open to any solution. Thanks.

Simple - add the following code to your landing page:

if (localStorage.getItem("visited")) {
    window.location.href = "webPlatform.html";
}
localStorage.setItem("visited", "true");

This checks if the localStorage variable exists - if it does, the user is redirected - if not, the variable is set.
