avatar-matt_raible.jpg Matt Raible

What are i18n and l10n? Internationalization (i18n) is the process of making your application capable of rendering its text in multiple languages. Localization (l10n) means your application has been coded in such a way that it meets language, cultural, or other requirements of a particular locale. These requirements can include formats for date, time, and currency, as well as symbols, icons, and colors, among many other things. i18n enables l10n. Why is i18n and l10n...

Reactive apps allow you to scale better if you’re dealing with lots of streaming data.

avatar-matt_raible.jpg Matt Raible

When I first started to learn Angular (it was called Angular 2 at the time), I was appalled by the number of files you needed to create to get a basic "Hello, World" example working.
