Moment-timezone is pretty great. However the moment library is no longer maintained, and there's some complications to its use due to it being mutable. Still works great though. Source: over 1 year ago

It was actually much easier to make than I thought it would be, thanks to Moment. - Source: dev.to / almost 2 years ago

The clock is in Javascript. Time zones in JavaScript historically are non-trivial since everything is based on the client clocktime. Fortunately, there is moment.js and moment-timezone-with-data.js that vastly simplify getting the current time at the NYSE. The clock keeps ticking correctly irregardless of which tab is active. I find the clock to be also functional since the WSBoy is worn over where I would... Source: over 2 years ago

I used the Moment-Timezone library, which returns, well, all the timezones! Super easy to get started with, just add using npm or yarn to add it, and then add import moment from 'moment-timezone'; to the top of your file. - Source: dev.to / over 2 years ago

I’m not exactly sure what you are trying to do but JavaScript Source Maps basically do this same thing with browsers and they use https://developers.google.com/closure/compiler/. Source: over 1 year ago

I'm using the Google Closure Compiler. I believe it has similar capabilities. Source: over 1 year ago

In a real world scenario you'd probably run the resulting JS through Closure Compiler. It would be nice to see how that affects both code size and performance. Source: over 1 year ago

Kind of funny that Google actually does have a product called the "Google Closure compiler". It creates different kinds of compilations though. https://developers.google.com/closure/compiler. - Source: Hacker News / over 1 year ago

Partially, depending on what's used it also optimizes the javascript code. See Google's closure compiler for more info. Source: about 2 years ago
