The `else` Clause
Conditional Statements have an optional else clause which can be used to specify a block of code to be executed in case the boolean expression evaluates to false.
The syntax is as follows:
if(boolean_expression)
{
// Code to execute if boolean_expression is true
}
else
{
// Code to execute if boolean_expression is false
}
This way we don't need to write multiple if-statements to check for opposite conditions, making the code shorter and neater.
1234567let age = 18; if(age >= 18) { console.log("The user is old enough to drive."); } else { console.log("The user is not old enough to drive"); }
In the code above, we simply used an else block instead of rewriting a separate if-statement.
1. What is the purpose of the else clause in an if-else statement?
2. What will be the output of the following code?
3. What happens if the if condition evaluates to true?
