How to Convert a JavaScript Date String from 'Sun May 11, 2014' to 'yyyy-mm-dd' Format?

Modifying JavaScript Dates to yyyy-mm-dd Format

Question: Convert a JavaScript date in the format "Sun May 11,2014" to "2014-05-11".

Initial Attempt:

One common approach involves splitting the date string, manipulating its components, and reassembling them. However, this method yielded the same original format.

Solution:

Embrace the built-in toISOString() method:

let yourDate = new Date();
yourDate.toISOString().split('T')[0];

This code returns an ISO 8601 timestamp, which aligns with the desired yyyy-mm-dd pattern.

Timezone Handling (Optional):

To handle time zone considerations, consider incorporating the following modifications suggested by @exbuddha:

const offset = yourDate.getTimezoneOffset();
yourDate = new Date(yourDate.getTime() - (offset * 60 * 1000));
return yourDate.toISOString().split('T')[0];
