5) What are Macros in Clojure?

Macros are mainly used to write the code generating routines which helps to provide the developer with a powerful way to tailor the languages to the needs of the developer.

6) Who invented the Clojure programming language?

11) What are the main purposes of the Clojure in JVM?

Clojure is mainly designed as a host programming language. It runs on the JVM and also provides interoperability in Java. While the language is running in Java it provides portability, stability, performance, and the security.

12) What are the phases in which the Clojure code processed?

There are three types of phases in which the Clojure Code processed and they are:

  • Read time
  • Compile time
  • Runtime

The updated version of Java 5 is supported by the Clojure programming language.

14) How can you display the Clojure Version in the REPL?

If you want to display the Clojure Version in the REPL then you have to use the command

Printin Clojure – Version

15) What are the type of the functions that are used in the Clojure programming language?

The following are the main types of functions that are used in the Clojure:

  • Anonymous function – These type of functions are simple functions that are not bound to a name.
