According to https://nodejs.org/en/

Node.js® is a JavaScript runtime built on Chrome's V8 JavaScript engine.

However, according to this answer, JavaScript is:

JavaScript = ECMAScript + DOM API;

and there is no DOM in Node.js runtime. (or is there?) Also quoting from the book: Professional JavaScript for Web Developers:

Though JavaScript and ECMAScript are often used synonymously, JavaScript is much more than just what is defined in ECMA-262. Indeed, a complete JavaScript implementation is made up of the following three distinct parts:

• The Core (ECMAScript)
• The Document Object Model (DOM)
• The Browser Object Model (BOM)

which supports the answer I link to.

Considering the facts above, isn 't it correct to say Node.js is a ECMAScript runtime? If not, what do we need to remove (or add?) if we wanted to fork Node.js and make it an ECMAScript runtime instead of a JavaScript runtime?
