Elixir - If statement
An if statement consists of a Boolean expression followed by one or more statements.
Syntax
The syntax of an if statement is as follows −
if boolean-statement do #Code to be executed if condition is satisfied end
If the Boolean expression evaluates to true, then the block of code inside the if statement will be executed. If the Boolean expression evaluates to false, then the first set of code after the end keyword of the given if statement will be executed.
Flow Diagram
Example
a = true if a === true do IO.puts "Variable a is true!" IO.puts "So this code block is executed" end IO.puts "Outside the if statement"
The above program will generate the following result −
Variable a is true! So this code block is executed Outside the if statement
