All the new features in ECMAScript 2023 (ES14)

The wheel of time has carved out another year, and with that comes a new official release of JavaScript: ECMAScript 2023, aka ECMAScript 14. Improvements this year include additions to arrays and support for shebang in ECMAScript files, as well as the expansion of symbol keys for weak collections. The changes are largely refinements as opposed to anything dramatic. Nevertheless, the compound effect is to continue evolving the language. Here’s a look at what’s new in JavaScript in 2023.

Understanding the spec

Before we dig into the details of the new version, it’s worth talking about the ECMAScript specification. You can always find the latest version of the ECMAScript spec hosted at https://tc39.es/ecma262/. If you want to look at the specification in a specific year, you can append that to the URL. For example, this year’s spec is hosted at https://tc39.es/ecma262/2023/.
