Ever wondered who actually decides how JavaScript evolves? In this episode, Jan-Niklas Wortmann sits down with Daniel Ehrenberg, President of Ecma International and long-time TC39 contributor, talking about how the language evolves—from vague idea to official spec.
We unpack how proposals move through the stages, the philosophy behind JavaScript’s gradual evolution, and why some ideas never make it into the spec. From syntax debates to ecosystem pressures and the role of Babel, bundlers, and browser vendors—this conversation gives you a rare inside look at how your favorite language changes.
Whether you’re a JS nerd, framework author, or just curious about why import() works the way it does, this episode pulls back the curtain.
