Property 'toGMTString' does not exist on type 'Date'

Question

I'm trying to use date function on Typescript:

let date = new Date();
let gmt = date.toGMTString();

Now error I got is:

Property 'toGMTString' does not exist on type 'Date'

So how to convert local date to GMT using typescript?

Other methods are working fine like getTime(), getDate(), etc.

Answer 1

toGMTString() is deprecated, that's why it is not included in Date typings. You can use toUTCString() instead.

Answer 2

You can simply do this:

let gmt = date['toGMTString']();
