Show how much time is left after later.js text parser applied

How to display what time is left after the later.js text parser applied?

For example, I want to know it before the setInterval started.

const later = require('later');

later.date.localTime();
const schedule = later.parse.text('at 12:40');

later.setInterval(() => {
    console.log('executed!');
}, schedule);
Solution

  • There is .next() method which calculates the future occurrences.

    Display the future occurrence

    Input:

    console.log(later.schedule(schedule).next());

    Output:

    2017-11-28T12:40:00.000Z

    Display 10 future occurrences

    Input

    console.log(later.schedule(schedule).next(10));

    Output

    [ 2017-11-28T12:40:00.000Z,
  2017-11-29T12:40:00.000Z,
