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 However the moment library is no longer maintained, and there's some complications to its use due to it being mutable.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

Example: You've got a main.js file that's as long as a Tolstoy novel. Fix: Use tools like UglifyJS or Terser to minify your code. They'll squeeze out all the unnecessary bits and give you a sleeker, faster-loading file. - Source: dev.to / 8 months ago

They can do it, it is just turned off by default and require more advanced configuration. https://github.com/terser/terser#cli-mangling-property-names.... - Source: Hacker News / 10 months ago

Minifying is a common practice for optimizing production code. (for example, using Terser to minify and mangle JavaScript). - Source: dev.to / 11 months ago

Terser is JavaScript compressor that can minified specific method names. - Source: dev.to / over 1 year ago

Every release build of React Native uses terser to reduce the size of your JavaScript. And it operation can be omitted for Staging/Beta builds. - Source: dev.to / over 1 year ago
