Break
Break statement can interrupt the cycle. For example.
str = "";
i = 0;
j = 100;
while(true){
i++;
j--;
if(j==i)break;
str = str + i + ':' + j + ',';
}
This code makes string with list of pairs of numbers while they are not equal.
Continue
Continue statement makes the transition to the next iteration of the loop.
arr = [0,2,4,5,6,1,24,36,12,531,42,49,81];
for(i=0;i<arr.length;i++){
if((Math.sqrt(arr[i])%1) > 0)continue;
print(arr[i])
}
This script output numbers from array which square roots is integer.
Labels
Labels help use break and continue in nested loops.
glob:for(i=0;i<10;i++){
for(j=0;j<10;j++){
if(i==j)continue glob;
print(i*10 + j)
}
}
