While-loop

While-loops are code blocks that are executed multiple times as long as the specified CONDITION is met. The behaviour of while-loops is very similar to do-while-loops, and in some cases it even might be better to use do-while than while-loops, so watch out for opportunities to replace while-loops with do-while loops.

Scheduled for release in Kipper v0.11.0

Syntax

while (CONDITION) STATEMENT;

Execution Schema

• Check CONDITION, if it exists, before running the STATEMENT. If CONDITION is false, then the loop will be stopped!
• Run STATEMENT if CONDITION was true.

Examples

// ✓ Simple loop
var var1: num = 0;
while (var1 <= 5) {
  var1++;
}
call print(f"'var1' is now '{var1}'"); // -> 'var1' is now '6'


// ✓ Simple loop, without braces
var var2: num = 0;
while (var2 > 0 && var2 <= 25)
  var2++;
call print(f"'var1' is now '{var2}'"); // -> 'var1' is now '0'

// X Infinite Loop - Avoid this, as it results in your program freezing/running forever
while (true) {
  call print("An unnecessary print!");
}
