Wrong question. There is no such thing as a language being better than another in general. Better for doing what, by whom, in what time and quality objectives ?

Have a look at the video. Having immutable values doesn't mean you have immutable variables / names.

Indeed, by immutability I really meant immutability of the values, but not of the name bindings. So I would say an optimal setup is to have a mutable execution environment which handles immutable values.

Well, what are your thoughts on the 'Write fewer tests, faster' section of the article?

Author here. I could be wrong of course, but this stems from my experience in using a REPL from JavaScript. I hit 2 sorts of hurdle with mutability there: 1- I wasn't sure what I was viewing in the REPL was what the code of interest wa

The compiled or interpreted nature of a language (or its runtime) is a fuzzy concept at best (Java is interpreted on the JVM in the sense that it emits bytecode that is interpreted by the JVM; the main implementation of Clojure JVM compiles

Of all the technical problems we face as programmers when managing codebases, lack of familiarity with a tool is pretty much the only one that never gets worse. Learning is what humans do best.

Thanks, it's good to know there's an established terminology. I'll do my research and update the article.

Clojure is almost 10 years old. I don't think this reasoning makes sense though, because from what I've seen most of the cruft in any language comes from the very early design decisions (both in what's included and what'

Zero technical benefits for sure, but it may help with ClojureScript's marketing. I've seen many JS developers outright dismiss ClojureScript / Closure because they don't want anything that involves Java - which is comp

This article raises an important and interesting problem, but would benefit from a lot more nuance. It seems to claim there is only one ubiquitous way people teach, learn and do mathematics, but that is not the case. In my view, using abstr

Rejecting a programming language feature because you find it constraining is just ignoring history. Arguments similar to yours have been used to dismiss Garbage Collection, type systems, and even the use of high-level languages, all of whic

On the other hand, in my experience, people who over-specialize tend to have very narrow perspectives on any software problem. If I had to choose between the guy who's done 10 years C# and the guy whose done 2 years C# and 2 years Java

I agree with you that you should pick a tool based on the project requirements, but you seem to imply that early-stage technologies are only suitable for science projects. A very simplistic perspective, and misguided advice for anyone facin

Would you agree to call Grunt a configuration tool? I have found the fact that Grunt lets you write full-featured JavaScript quite useful. In 95% of cases, of course, you want to write your configuration in a declarative, JSON-like form, bu
