Sometimes Templates are not enough to express complex behaviors. Bindings are used to transform inputs into other inputs using javascript code.
Example:
return context.any_id == "test" ? "this is a test" : "not a test";
The body of the binding contains a context object, which contains every other input and bindings. All inputs are expressed as Strings, but context will automatically add extensions of more natural values. For example a toggle of id is_on will have a boolean context context.is_on_Bool.
The return keyword can be omitted for single line statements.
Since bindings can call each other, the user needs to be careful not to create infinite recursions by having binding calling each other.
