JavaScript
The Workers platform is designed to be JavaScript standards compliant ↗ and web-interoperable, and supports JavaScript standards, as defined by TC39 ↗ (ECMAScript). Wherever possible, it uses web platform APIs, so that code can be reused across client and server, as well as across WinterCG ↗ JavaScript runtimes.
Refer to Runtime APIs for more information on specific JavaScript APIs available in Workers.
