While
Repeat code while a Boolean condition
is true.
while(true) {
}
The while loop has a condition that evaluates to a Boolean value. After the do
keyword, add the code that you want to run while the condition
is true
. The while loop concludes with end while
.
The condition is tested before any code runs. Which means that if the condition is false, the code inside the loop doesn't execute.
Example: diagonal line
The following example uses a while loop to make a diagonal line on the LED screen (points 0, 0
, 1, 1
, 2, 2
, 3, 3
, 4, 4
).
let index = 4;
while(index >= 0) {
led.plot(index, index);
index--;
}
