I was making graphs in node, and finally got it working.
In my code I have to define node which is an number for each label / node in the graph.
This graph has node set to 15:
And when I set node to 5:
This took me so long. It finally works :3
Here is 198, which is the limit. Just because I feel like generating this:
And here is 2 nodes:
The problem
Then I thought, what is the other limit? I think 1 will crash, let’s try it:
Well looks like that worked. Funny. Thought I would have to write a hardcoded way around this.
Okay, then 0. 0 should give my a Devision by 0 exception Since I divide by the amount of nodes somewhere. minutesDifference / amount. Okay so let’s try 0 nodes:
What? I mean this is the result I want, but where is the exception?
This is weird. Okay let’s try -1 nodes. Just cause funy and I want it to crash.
-1 nodes:
Hoh?? how? What? Why?
This should give me an error, Like why am I not getting errors????
Okay let’s try 3.14 nodes (cause in#code/javascript an float and int are both number):
WHAT?? I never told it to round up?? WHY is this happening???
Okay let’s try null for shits n giggles:
Okay about as expected, but also not, since it’s not a number. how can 1234/ null = a number???
Okay let’s try NaN nodes:
HOW DOES IT NOT CRASSHHHH????
Okay let’s try undefinded nodes:
Okay I hate this, Let’s see what I can find that does make it crash.
results
I made a table with these scuffed results.
| value | outcome | is this a logical result? |
|---|---|---|
| 1 | 1 node | yes |
| 0 | empty graph | yes |
| 199 | CRASHES | yes |
| -1 | empty graph | no |
| NaN | empty graph | no |
| null | empty graph | no |
| undefined | empty graph | no |
| “henk” | empty graph | no |
| {} | empty graph | no |
| {“henk”: false} | empty graph | no |
| [] | empty graph | maybe |
| [“henk”, “henk”] | empty graph | no |
| true | 1 node | kinda |
| false | empty graph | kinda |
Okay so why did I write this?
Javascript handles way too much, okay true and false being turned into 1 and 0 is fair enough, but IN WHAT WORLD DOES NOT A NUMBER aka NaN == 0.
Or I’d expect that it would look at the lenght of the list with ["henk", "henk"], cause if you are going to handle this, that seems the most logical, but no it is equal to / less than 0. OK??
I actually was mentally prepared to limit what the user is allowed to request, but I don’t need to apparently. I HATE THIS AAHHAHAHAHHAHA
