LitElement Handling Data section is not acurate

[zevdg]

LitElement will pass data to an element as properties, as long as the property is defined on the element's prototype. Otherwise it will fallback to passing data as attributes.

I just asked on the LitElement slack and this is not true. lit-html uses attributes by default and has an alternate syntax to explicitly pass a property instead, just like Vue.

P.S. Historically, this one the other way around (properties by default and special syntax to explicitly specify attributes). This was changed in lit-html 0.11 via lit/lit#398

Good catch. We were originally testing an older version of lit.
