Doesn't to deserializing string format of Date to Date object #5671

Closed corocoto closed 3 years ago

Description

I trying to deserialize string format of Date to Date object, but it's still string type.

I thought it was done automatically after reading the #4592 issue. Maybe I understood it somehow differently. And if it is, how can I make it right?

Steps to Reproduce

  1. Declare property currentDate like this: 
    static get properties(){
currentDate : {
    type  : Date,
value : '2020-08-04T15:08:58.037Z', // ISO format
},
}
  2. Add checking inside of connectedCallback: 
    connectedCallback(){
super.connectedCallback();
console.log(this.currentDate.constructor === Date);
}

Expected Results

Should display true.

Actual Results

Display false.

Ah, sorry. It's my wrong. It will be work if I set string value ('2020-08-04T15:08:58.037Z') as attribute's value.

So it looks like this: 

<my-calendar current-date="2020-08-04T15:08:58.037Z"></my-calendar>
