Shorthand attribute/prop syntax

[jasonlfunk]

What problem does this feature solve?

I often find myself writing code like this:

<component :data='data' :name='name' :email='email'></component>

This code is redundant and isn't fun to write.

What does the proposed API look like?

Using es6 Object Literal Shorthand as inspiration, the component could instead be written like this:

<component :data :name :email></component>
