Decorators are a big and important feature for ECMAScript. The standardization of decorators has been ongoing since 2018. During this time, the proposal for extending JavaScript classes has evolved based on discussions, as well as feedback from users and implementers. In this talk, one of the champions of this design pattern, Daniel Ehrenberg, will share the history of the proposal, which is now in Stage 3 of ECMA TC39's standardization process.

TC39 is the standards committee that designs the JavaScript language (sometimes called ECMAScript). The panel will feature a range of committee members and they will answer to questions about the past, present and future of JavaScript!

Internationalization in JavaScript and on the web platform is very complicated, but also vastly important for us developers in order to build accessible and intelligible interfaces. Thankfully, Unicode Consortium's MessageFormat working group and TC39 have been hard at work standardizing the next generation of i18n tooling that aims to unify analogous non-standard tools in use today while approaching this problem from a fresh perspective.

Join me along this tour of i18n in JavaScript, discover some of the newest additions to the toolkit and learn about the ongoing MessageFormat proposal and how it aims to radically improve the developer experience.
