if/else Statement

The if/else statement executes a block of code if a specified condition is true. If the condition is false, another block of code can be executed.

Use comparison & logical operators to create a condition that's either true or false

In ScarLang we have the following conditional statements:

  • Use if to specify a block of code to be executed, if a specified condition is true
  • Use else to specify a block of code to be executed, if the same condition is false
  • Use else if to specify a new condition to test, if the first condition is false

Syntax

The if statement specifies a block of code to be executed if a condition is true: 

1
2
3
if (condition) {
  # block of code to be executed if the condition is true
}

The else statement specifies a block of code to be executed if the condition is false: 

1
2
3
4
5
if (condition) {
  # block of code to be executed if the condition is true
} else {
  # block of code to be executed if the condition is false
}

The else if statement specifies a new condition if the first condition is false: 

1
2
3
4
5
6
7
if (condition1) {
  # block of code to be executed if condition1 is true
} else if (condition2) {
  # block of code to be executed if the condition1 is false and condition2 is true
} else {
  # block of code to be executed if the condition1 is false and condition2 is false
}

Single line if statement

There is also a single line version of the if statement. It is not possible to use else and else if with this single line if statement. 

1
if (5 == 5) -> print("5 is 5!")
