Logging Events

• log.sync - fires every time the template synchronizes
• log.listen - fires when View subscribes a model or a collection
• log.template - fires on template warnings

You can subscribe for view events like that:

let logger = {
  "log:sync log:template": function( msg: string, ...args: any[] ): void {
      console.log( `LOG(${this.cid}):`, msg, args );
   }
};

new FooView({ logger: logger });
