What's next in JavaScript (a TC39 update) (JS Party #305)

Daniel Ehrenberg (software engineer at Bloomberg, web standards author / champion & VP of ECMA International) joins us to discuss new features that have landed in JavaScript and to preview what’s cooking in various standards bodies across the web platform.

We cover a wide array (get it?) of topics from improvements to built-ins such as Promises, Maps & Sets, as well as new primitives like Records, Tuples & Temporal. We round out this epic discussion with a look at cross-project standardization efforts like WinterCG, open source sustainability & how Bloomberg’s open source program gives back in important projects in the web ecosystem.

Correction: Near the end, Dan misspoke when said the Bloomberg FOSS Fund was done in partnership with Bloomberg Philanthropies. It was actually done together with Bloomberg’s Corporate Philanthropy team.
