Day 4 seems to have been an outlier in being weirdly more difficult? This was easier again.

How do you decode these?

Day 9 - Discussion
I started a bit late because I had a class today. The first part seems like it's meant to be used with linked lists. I tried to be clever with the second part [by representing the disk as file indices much like filesystems], but that didn't work out so I had to do it data recovery style.

Also, this day made me think of a weird feature for for-loops (and any other loop really): a break that return some value. So something like this:

for (let i in something) {
    if (something[i] == solution)
        break i;
} catch (i) {
    // do something with i
} else {
    // what to do when the break carries no value
}
// everything else is normal

In this example, when the condition is met, the for-loop breaks, and execution continues on the `catch` block first. Otherwise, it continues to the `else` block (if it's defined). After that, execution goes as usual.

I think this is best fit with pattern matching, but that doesn't feel like JavaScript, so no examples for that here.

It's probably not related to this?

You can make this with exceptions (at least in python, and this is untested but the concept should work):

class LoopReturnException(Exception):
    def __init__(self, value):
        self.value = value
 
try:
    for i in range(10):
        if i == 5:
            raise LoopReturnException(some_value)
except LoopReturnException as e:
    print(f'Loop returned {e.value}')
else:
    print('Loop did not return a value')

for(int i = 0; i < count; i++){
    if([something]){
        puts("Early Exit!");
        goto early;
    }
}
puts("Normal Exit!");
early:
; //null statement does nothing. Here because a label must not be at the end of a code block. Not required if there is more code below it other than an end of a blocks.

normalExit=true
for i in range(10):
    if [something]:
        normalExit=false
        print("Early Exit")
        break
if normalExit:
    print("Normal Exit")

Exceptions are for error handling, not exiting loops.

Anyone aware of for-else syntax in Python? The else runs unless you break.
