QUESTION
I'm learning about data structures and I'm trying to create a linked list. My problem is that one of my two while cycles aren't reaching the end of the linked list (it stops in the first element). They're not exactly equal, but they're very similar; the first cycle (the working one) runs while the current list pointer isn't null, and the second runs while the the next list pointer isn't null. The compiler isn't showing any errors and the program doesn't stop working when opened. Also is important to say that this isn't my main code, it's a test code that I wrote to try to solve the problem myself (unfortunately, without success) - but it serves to illustrate the problem.

QUESTION
I have a canvas with a drawn object on it. I also have save as JSON and load from JSON functionality. The drawn object is drawn and isn't selectable when you load the app, this is how I want it to remain, but when you load this from JSON it's selectable. How can I make sure that these properties remain through the saving + loading process?
Here is a JSFiddle where you can see what I mean. Note the line; when you load the app, it's untouchable. But if you save the JSON and then load it, the line becomes selectable.

QUESTION
I have a FabricJS canvas (1.7.22) with a few buttons to add images and text. I also have a textarea
which I can use to load the canvas JSON for copying and to load to the canvas for later editing.
I want to expedite the process by being able to save the canvas JSON as a file to my computer and be able to load the file onto the canvas later.
I feel like I have the essential functionality but how might I achieve the above for better usability?
