Does Node.js support let keyword?
javascript, node.js, scope
Solution
Yes, the `let` keyword is supported, provided you run Node with the `--harmony` flag. However, I wouldn't recommend using `let` in production software. (by the way, you could have found this answer via search, before you asked a new question)
Problem
In Javascript 1.7 the `let` keyword introduces block scope. This is arguably the most needed feature of Javascript and I was wondering if Node.js supports it. Part of my difficult in ascertaining this is Node runs Google's V8 engine, which comes from such and such standard and I don't know how these line up with the Javascript x.y version numbers.
