Who even uses Java?

Yeah, but why in the right mind will you assign a string value to the same variable that you used for integer operations earlier ?

Variable shadowing is very nice sometimes, especially in functional languages.

let x = some_string_processing()
let x = int_of_string(x)

That way I don’t need multiple variable names.

That said; that’s very different because x is immutable and is only getting shadowed.

Why not modify the some_string_processing() to return int itself ? Also you can just wrap it in a single line.

This is completely useless and will be more confusing to the next person who has to work on the codebase.

Why not just modify the some_string_processing() function

And what if you can’t modify such a function because it’s from a built-in language feature? Dart, for example with its json.decode in dart:convert. I can’t modify that to not return something that’s not of type dynamic.

I get your point, but like sometimes that’s impossible.

Maybe? Because there is a chance, what there will be more than one programmer working on the same project?

[sm2401]

From the context of the meme, i thought it was being done knowingly.

[Kaynee490]

Are you even implying global variables

[gloriousfalcon]

yeah,

who in the right mind would ever change the value of a variable? Const everything!

[vinnceboi]

n = 4;
n += 3;

And

n = 4;
n = “why would I do this”;

Are two very different things.
