The switch Keyword
Explore how to use the switch keyword in ReasonML to handle multiple conditional cases based on varying values. Understand its syntax, the use of the pipe operator for case separation, and how to implement default cases with the underscore operator. This lesson also covers handling tuples within switch expressions to enhance your functional programming skills in ReasonML.
We'll cover the following...
What is the switch Keyword?
The switch keyword allows us to specify the different actions the program can perform based on the value of a particular expression.
In an if-else expression, the condition always returns a boolean. This means that it can only cater for two cases: true and false.
With a switch keyword, the conditional expression is not restricted to booleans. Hence, we can define the behavior of the program for several cases. These cases are separated by the pipe operator, ...
