Reassignment


#1

Total newby here, when would I want to reassign a variable rather than finding where I first put it in and changing it there?


#2

well, what if the variable contains user input? You can’t change what the users enter into your program. Or data from a database, there are plenty of situation where re-assigning is preferable.

you will see the re-assign is very common practice, its certainly has its value


#3

I think you might be mixing up variables and values o.o

variables hold references to values, so that you can use those values again later

And you’d reassign a variable to update its value, perhaps you want to increase it by 1 - you’d do that by computing a new value and assigning the variable to that instead
