How do I read a Clojure code?
Here are three really important ways experts read Clojure.
- Focus on the first thing after the parens. In Ruby code, your eyes often use punctuation to find the meaning of code.
- Indentation means scoping. Another common complaint is how much nesting is done in Lisps.
- Learn the evaluation direction.

Is clojure difficult to learn?
I got into clojure last year after spending a few uninspiring years with python. It was a much slower process as compared to jumping into python or go but it made me a more aware programmer. This process was filled with many stumbling blocks which I am going to talk about.
Does Clojure have garbage collection?
Clojure creates so much “ephemeral” garbage, it’s important to be able to allocate and collect it quickly. Clojure’s data structures exercise the JVM’s fast GC. While using them is never going to be as fast as pure Java, the JVM does allow Clojure to be practical.
What’s the first line of code in Clojure?
Our first Clojure code is, of course, printing “Hello, world!”. Here, we invoke the function println with the argument Hello, world!. We call the invocation of function applying the function to data in Clojure or other functional programming language. The entire line of the code (….) is called a form in Clojure.
Is it hard to learn the language Clojure?
Clojure is a functional programming language and learning functional programming languages is sometimes hard if you’ve only had experiences with imperative languages.
How is the symbol resolution done in Clojure?
Like previous example, Clojure tries to resolve a. However, this time Clojure resolves a to “AAA”, instead of aaa. Each let will create a scope and symbol resolution is done inside the let where the symbol is resolved. Also notice that the inner let does not override the scope of outer let.
