Also to be clear, if you are already in the Elixir web ecosystem, EEx (Embedded Elixir) templates are what you currently write for regular server HTML rendering. LiveEEx allows you to take those same templates and support the diffing optimizations the post shows off, so labeling it "another kind of markup script" isn't accurate in this context.

On one hand I kind of agree. It's a special syntax, which is one of the reasons why I personally dislike Vue and Angular, etc.

However, pragmatically, it's minimal and all the guts will be in Elixir - where the people probably most interested in LiveView will be spending most of their time anyway. So it's a net win imho.

The additional markup is very minimal: phx-click, phx-change, phx-submit, phx-keypress, phx-keydown, phx-keydown, phx-error .etc
