Self-Editing Javascript?

[SuperJedi224]

Just wondering- is there any way to write a script that edits itself or another script when an event is triggered?
Maybe something like this:

01: variable=1
02: If variable=1
03: Create (Image)
03: When (Image) is clicked:
04: Replace Line 01 position 10 with "0"
05: End
06: End
07: End

Would something like this be possible in Javascipt (with the change in line 4 actually affecting the source code)? I can't find any tutorials for this.

It's less a case of "self-editing" in your example but simply changing the variable. So your line 4 psuedocode could simply be "set variable to 0"

Are you going by experience from another language where you can't change/don't have variables? (that said, I can't think of any that don't )

I mean having the code rewrite itself so in later instances the initial value is different.

What would be prompting a change in the initial value?

It might be easier if you explain what it is you're wanting to do, because the example you've given above wouldn't even do anything.

You might find some of these resources helpful as well, specifically this one about variables.

I'm not sure you fully grasp the concept of a variable if you ask this.

But, no, there is no way for this to happen. That's just not how JS works. There is no reason for that to need to happen, either.

Also to add to the voices above, note that this wouldn't be a way to store values over time, as a page reload would reset the variable to the original default. If you want to set a default and store it, you would need to use forms or AJAX to store the variable on the server side.
