moment js: custom format string to day duration

I'm have a rather wiered string with time. Something like this - "2.23:59:59.99". That means that first number before dot is a day count (2 days) and other is a time count - 23 hours 59 minutes 59 seconds and 9900 - milliseconds (or maybe 99 milliseconds). So I need to convert it to decimal number, like 2.99. How can I do it using moment.js ?

You can simply create a moment duration from your "2.23:59:59.99" string

As of 2.1.0, moment supports parsing ASP.NET style time spans. The following formats are supported.

The format is an hour, minute, second string separated by colons like 23:59:59. The number of days can be prefixed with a dot separator like so 7.23:59:59. Partial seconds are supported as well 23:59:59.999.

and then get its values in days using asDays()

moment.duration().asDays() gets the length of the duration in days.

To get "2.23:59:59.99" back from 2.99, you can create a duration using moment.duration(Number, String) and use format() method of moment-duration-format plug-in (using precision parameter)

// 2.23:59:59.99 to 2.99
const dur1 = moment.duration("2.23:59:59.99");
const durAsDays = dur1.asDays();
console.log(durAsDays);

// 2.99 to 2.23:59:59.99
const dur2 = moment.duration(durAsDays, 'days');
console.log(dur2.format("d.HH:mm:ss", 2));

moment.duration('2.23:59:59.99').asDays()

Refer to Moment JS .asDays() method
