JavaScript Standards and ECMAScript

The JavaScript programming language is governed by a standard known as ECMAScript, which was established by the ECMA International organization. The podcast highlights that the name 'JavaScript' is protected by a trademark held by Oracle, complicating discussions about the language's identity. A movement is underway to free this trademark and allow for widespread use of the term 'JavaScript' instead of 'ECMAScript.' This initiative is being led by Ryan Dahl, founder of the Deno runtime, who has also penned a blog post detailing the historical context and the current quest for trademark liberation.
