Only a clarifying point to add about Lit: tagged templates provide templating and have native support, all Lit does is provide API extensions for reactivity, ie state management. So when a portion of a template is associated with an object, only that part is updated due to how the libraries work. And this is fundamentally all the it provides (unless I've misunderstood something). Lit-html provides functional state+template views while LitElement provides the OO/class oriented lifecycle approach--collectively now rebranded as "Lit". https://lit.dev/ Please call out corrections as needed.
