What language does the XD plugin API support?

Question

I saw a pre-launch FAQ on the Adobe Tech Blog that says XD plugins will "be written in modern JavaScript", but what does that mean exactly?

• Can I use ES5?
• What about ES6/ES2015 features?
• Does it support Adobe ExtendScript?

Answer 1

Adobe XD Extensibility is built on top of a Modern JavaScript engine, which means that it understands both older versions of JavaScript (ES5) and the newer variants (ES6 / ES2015, etc.). ExtendScript is not supported for Adobe XD plugins.

Some useful features are listed below:

• ES5
  • Getters / Setters
  • Array#map, Array#foreach, etc.
• ES6/ES2015+
  • Promises
  • Template literals
  • Classes
  • const and let (block-scoped variables)
  • Destructuring, default and named parameters
  • Symbols
  • Iterators
  • async and await

That said, if you're not familiar with ES2015+, you're not required to use it.
