What is toUTCString() in JavaScript?

JavaScript has a number of built-in date and time functions that allow you to work with dates and times in your scripts. One of these functions is to`UTCString()`, which converts a JavaScript Date object to a UTC string.

The toUTCString() function takes a Date object as its parameter and returns a string in UTC format. The UTC format is based on Coordinated Universal Time (UTC), which is the international time standard. UTC is the time standard that all time zones are based on, and it is always the same, regardless of where you are in the world.

The toUTCString() function returns a string in the following format: "YYYY-MM-DDThh:mm:ssZ".

The "YYYY-MM-DDThh:mm:ssZ" part of the string is the UTC time.

The "YYYY" part is the year, the "MM" part is the month, the "DD" part is the day, the "hh" part is the hour, the "mm" part is the minute, and the "ss" part is the second. The "Z" at the end of the string indicates that the time is in UTC time.

Here is an example of how to use the toUTCString() function:

var date = new Date("July 4, 2016");
var utcString = date.toUTCString();
console.log(utcString); // "2016-07-04T19:00:00Z"

In this example, we create a new Date object for July 4, 2016. We then use the toUTCString() function to convert the date to a UTC string. The console.log() function then prints the UTC string to the console.
