JavaScript: Get a string of the form HH:MM:SS from a Date object

JavaScript fundamental (ES6 Syntax): Exercise-221 with Solution

Time from Date Object

Write a JavaScript program to get a string like HH:MM:SS from a Date object.

• Use Date.prototype.toTimeString() and String.prototype.slice() to get the HH:MM:SS part of a given Date object.

Sample Solution:

JavaScript Code:

// Define a function 'getColonTimeFromDate' that extracts the time portion in HH:MM:SS format from a Date object
const getColonTimeFromDate = date =>
  // Convert the date to a time string using 'toTimeString' and extract the first 8 characters (HH:MM:SS)
  date.toTimeString().slice(0, 8);

// Log the result of calling 'getColonTimeFromDate' with the current date
console.log(getColonTimeFromDate(new Date())); // Output: Current time in HH:MM:SS format

Output:

16:39:53
