Next Experience global variables are used in client scripts to determine whether Next Experience is applied to a page.

NOW.isUsingPolaris
Returns true if Next Experience is applied to the current page.
NOW.isPolarisWrapper
Returns true if the page is running in the Next Experience Unified Navigation. This global variable exists only in the Unified Navigation.

For more information about the Unified Navigation, see Using the Next Experience Unified Navigation.

Example

Client script:

// Reload the current page in the unified navigator if not currently in the unified nav
if (NOW.isUsingPolaris && (!top.NOW || top.NOW.isPolarisWrapper !== "true")) {
    var currentPath = window.location.pathname + window.location.search;
    top.window.location.href = "/now/nav/ui/classic/params/target/" + encodeURIComponent(currentPath)
}
