Yeah, &#x27;ship&#x27; means different things in different contexts. In the context of your original comment, node stable is getting arrow functions within a week of Chrome stable getting them.<p>In general, io.js has been very good at picking up stable V8 soon after it ships in Chrome. The exception was V8 4.3, which was not picked up because of API compatibility issues.<p>This is not a problem for Chrome because chrome doesn&#x27;t expose the V8 C++ API to large body of third party module writers like Node does. It takes time to deal with some API changes.
