Deno joins JavaScript standardization effort

The developers of Deno, the TypeScript / JavaScript runtime positioned as an alternative to Node.js, have joined the standards body overseeing the development of the JavaScript standard.

In a December 13 blog post on the Deno company website, engineer Luca Casonato noted that the company is now a member of ECMA International, the organization overseeing ECMA-262, the ECMAScript standard that underpins JavaScript. Deno will participate with other ECMA members and the wider JS community in upcoming iterations of JavaScript through the TC39 working group.

Deno will push for feature enhancements that benefit everyone, but especially server-side JavaScript users, Casonato wrote. Features Deno expects to pursue include:

  • Better support for non-JS assets in the ES module graph.
  • Improved support for explicit resource management.
  • Extended standard library functions for asynchronous iteration.

Deno also wants to pursue a closer alignment between TypeScript and JavaScript. Casonato will be Deno’s main representative at TC39. He invites suggestions on improvements to JavaScript, to be emailed to [email protected] or via Twitter to @ lcas.dev.

ECMAScript 2021, the most recent version of the JavaScript standard, was released in June, offering functionality for promises and strings. Also this year, the TC39 group in July formed a task force, TC39-TG3, to focus on JavaScript security, seeking to help developers create secure programs.
