PropDefinition

By defining a wildcard property ("*") on the prototype, this will supply a default behavior for every property in the list. The default wildcard "*" definition makes every property run through the "observable" types converter. It looks like:

{
    "*": {
        type: "observable"
    }
}

Setting the wildcard is useful when all properties should be converted to a particular type.

const Person = DefineList.extend( { /* ... */ } );

const People = DefineList.extend( {
    "*": "string",
    "#": Person
} );

const people = new People();

people.set( "age", 21 );
people.age; //-> "21"
