Statements: Break and Continue
The break and continue statements are used to control the flow of a loop.
syntax
BreakStatement :
breakLiteralIntegerExpression?;
ContinueStatement :
continueLiteralIntegerExpression?;
Break
The break statement is used to exit a loop early.
for $i = 0; $i < 10; $i++ {
if $i == 5 {
break;
}
// ...
}
You can also use a level to break out of nested loops.
for $i = 0; $i < 10; $i++ {
for $j = 0; $j < 10; $j++ {
if $i == 5 && $j == 5 {
break 2;
}
// ...
}
}
WARNING
The level must be a literal integer.
function example(): void {
while $condition {
// ...
while $another_condition {
// ...
if $something {
break $level;
}
}
}
}
The code above will result in the following error:
error[P0042]: unexpected variable, expected `;`

Continue
The continue statement is used to skip the rest of the current iteration of a loop.
for $i = 0; $i < 10; $i++ {
if $i == 5 {
continue;
}
// ...
}
You can also use a level to continue to the next iteration of a nested loop.
for $i = 0; $i < 10; $i++ {
for $j = 0; $j < 10; $j++ {
if $i == 5 && $j == 5 {
continue 2;
}
// ...
}
}
