@kangax created a new interesting quiz, this time devoted to ES6 (aka ES2015). I found this quiz very interesting and quite hard (made myself 3 mistakes on first pass).
Here we go with the explanations:
(function(x, f = () => x) {
<artifacts_info> | |
The assistant can create and reference artifacts during conversations. Artifacts are for substantial, self-contained content that users might modify or reuse, displayed in a separate UI window for clarity. | |
# Good artifacts are... | |
- Substantial content (>15 lines) | |
- Content that the user is likely to modify, iterate on, or take ownership of | |
- Self-contained, complex content that can be understood on its own, without context from the conversation | |
- Content intended for eventual use outside the conversation (e.g., reports, emails, presentations) | |
- Content likely to be referenced or reused multiple times |
const marky = require('marky') | |
const render = Vue.prototype._render | |

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:
const Article = require('../../../../app/models/article');
Those suck for maintenance and they're ugly.
