|---|---|
| 1 | If Statement
In Clojure, the condition is an expression which evaluates it to be either true or false. ‘If’ the condition is true, then statement#1 will be executed, else statement#2 will be executed. |
| 2 | If/do Expression
The ‘if-do’ expression in Clojure is used to allow multiple expressions to be executed for each branch of the ‘if’ statement. |
| 3 | Nested If Statement
Multiple ‘if’ statements embedded inside each other. |
| 4 | Case Statement
Clojure offers the ‘case’ statement which is similar to the ‘switch’ statement available in the Java programming language. |
| 5 | Cond Statement
Clojure offers another evaluation statement called the ‘cond’ statement. This statement takes a set of test/expression pairs. |
