'Invalid date' in momentjs

Question

I have a date:

let date = "15:00";

and I want to process it to format: 2019-09-26T15:00:00.000Z , but momentjs get and invalid date error.

I tried using moment(date).format('LTS');

Answer 1

let date = "15:00"
let m = moment(date, "HH:mm");
m.utc().format();

Note: This will use current date's date as default since you're only passing the time.

Answer 2

You should add the format of value also, like this:

let date = "15:00";

let m = moment(date, 'HH:mm').toISOString();
console.log(m);

Because you need something like this 2019-09-26T15:00:00.000Z , it's better to use the toISOString function, rather than the format .
