Question

I want to display default date values to Lightning-Input, how to get the Today Date and Current year date in Javascript. Format should be :- May 15, 2020

Answer 1

The following can get you current date

JS

connectedCallback(){
    var today = new Date();
    this.date=today.toISOString();
    console.log(today.toISOString())
    var last=new Date(new Date().getFullYear(), 11, 32);
    this.date1=last.toISOString();
}

Answer 2

Unfortunately, the answer from @User6670 is going to give you time zone headaches where the "today" calculation is concerned. Say you have a user in California who accesses your component on May 15, 2020 at 5pm (their time). Since they have a time zone offset of 7 hours, they will see "May 16, 2020" -- the date in UTC.

To fix this, adjust for the user's local time zone:

// Get the current date/time in UTC
let rightNow = new Date();

// Adjust for the user's time zone
rightNow.setMinutes(
    new Date().getMinutes() - new Date().getTimezoneOffset()
);

// Return the date in "YYYY-MM-DD" format
let yyyyMmDd = rightNow.toISOString().slice(0,10);
console.log(yyyyMmDd); // Displays the user's current date, e.g. "2020-05-15"
