How to get date object from date string format - javascript

I'm trying to convert a date string to date format, something like this:
var date = "07/11/2015"; //format is mm/dd/yyyy
Now I want it to be in this format:
date = Tue Sep 01 2015 00:00:00 GMT+0530 (India Standard Time)
Can anyone suggest a way to achieve it. Thanks in advance!

var date = "07/11/2015";
alert(new Date(date)); //Sat Jul 11 2015 00:00:00 GMT+0530 (India Standard Time)

Your date seems to be a standard string representation of new Date(), you can get the desired format by using new Date().toISOString()
console.log(new Date().toString())
console.log(new Date().toISOString())
// To create it from string
const dateStr = "Fri Apr 20 2020 00:00:00 GMT+0530 (India Standard Time)"
console.log(new Date(dateStr).toISOString())
Anurag Srivastava's answer shows how you should parse the string and format it in the required format (given that the string is in one of the two formats supported by ECMA-262 and considering Why does Date.parse give incorrect results?).
Note that "Fri Apr 20 2020 00:00:00 GMT+0530 (India Standard Time)" is the same instant in time as "2020-04-19T18:30:00.000Z". The first string is offset from UTC by 5 hr 30 min, so the equivalent UTC time is 5 hr 30 min earlier, which means the date is the previous day.
You haven't given a reason why you want to treat it as UTC and not consider the offset, so I don't think you should.
However, if you do have a good reason to parse it as UTC and ignore the supplied offset, then you can either:
Modify the input string to set the offset as +0 and parse it using the built–in parser
Parse the string yourself and treat it as UTC
let s = "Fri Apr 20 2020 00:00:00 GMT+0530 (India Standard Time)";
// #1 Modify the input string, setting the offset to +0
let d = new Date(s.replace(/GMT.*$/,'GMT+0000')).toISOString();
console.log(d.toISOString());
// #2 Bespoke parser
function parseAsUTC(s) {
let months = ['jan','feb','mar','apr','may','jun',
'jul','aug','sep','oct','nov','dec'];
let b = s.split(/\W/);
return new Date(Date.UTC(b[3], months.indexOf(b[1].toLowerCase()),
b[2], b[4], b[5], b[6]));
}
console.log(parseAsUTC(s).toISOString());

How to get `Fri Oct 25 2019` from a date object (Fri Oct 25 2019 15:27:01 GMT+0530 (India Standard Time))?

How can I get Fri Oct 25 2019 from a date object as below?
Fri Oct 25 2019 15:27:01 GMT+0530 (India Standard Time)
Use the toDateString() function from JavaScript.
let d = new Date();
// note : the actual display output depend on your browser/system settings (locale)
console.log(d.toString());
console.log(d.toDateString());
This will take the first "date only" part of the string that is displayed from the date object.
It could also be done with string manipulation, but this function is actually intended for this usecase, so probably clearer.
