Conditionals

In Dark Elixir, Conditionals are implemented using If statements The if statement is a fundamental control flow statement in Dark Elixir that allows you to conditionally execute code based on a specified condition.

Syntax​

if (<condition>) do
    // body
end

if: The if keyword marks the start of the if statement. <condition>: This represents the expression or condition that is evaluated. If the condition is true, the code block is executed. If the condition is false, the code block is skipped. do: The do keyword denotes the start of the code block to be executed if the condition is true. end: The end keyword marks the end of the if statement.

Example​

Here's an example of how the if statement can be used in Dark Elixir:

if (age >= 18) do
  // Code block executed if the condition is true
  print("You are an adult.")
end

Else if Ladder​

In addition to the if statement, Dark Elixir also supports an "else if" ladder construct to handle multiple conditions. The syntax for an "else if" ladder is as follows:

if <condition1> do
  // Code block executed if condition1 is true
elif <condition2> do
  // Code block executed if condition1 is false and condition2 is true
else
  // Code block executed if all previous conditions are false
end

Usage Recommendations​

  • Ensure that the conditions within the if statements evaluate to boolean values (true or false).
  • Properly indent the code blocks within the if statements for readability.
  • Consider using an else clause to handle cases when none of the conditions are true.
