Conditional Expressions
Review

Great job getting to the end of this lesson. Let’s review the content we learned:

  • Conditional expressions control the flow of execution in a program.
  • An if expression executes a block of code when the value of its condition is true.
  • An else expression executes code when none of the previous expressions have a true value.
  • Comparison operators like >, <, >=, and <= are used to compare two values to determine a true or false value.
  • The == operator checks if two values are equivalent while the != operator checks if two values are not equivalent.
  • The logical AND operator (&&) returns true when two Boolean expressions being compared are both true.
  • The logical OR operator (||) returns true when at least one Boolean expression being compared is true.
  • The logical NOT operator (!) negates the value of a Boolean expression.
  • else-if expressions are used to add more conditions to a traditional if/else statement.
  • A nested conditional is a conditional that appears inside of another conditional.
  • A when expression evaluates the value of a variable or expression in order to dictate the flow of a program.
  • The range operator .. creates a consecutive succession of values.
