Salesforce Communities : Building Login Page with LWC Component

Salesforce communities with LWC combination is evolving bigger in this 2020. Unfortunately some features that works well with the Aura Component is not working as expected with LWC, like the Community Navigation. Similarly, aura.redirect property that redirects on successful login fails to navigate with LWC component.

2. Single component – when there are only one item found in the DOM
3. Array of components – when there are more than an item found in the DOM
