JavaScript

This is too stupid so I had to check.

Fuck me.

People that try to do mathematical operations with strings blaming the programming language that had a stated design goal to do its best and try to keep running scripts that make no sense because they realized it would be used by people that have no idea what they are doing. Clearly they were right.

Imagine doing math with strings and then blaming the language not yourself

To start off... Using arithmetic operators on strings in combination with integers is a pure skill issue. Let's disregard this.

If you were to use + where one part is a string, it's natural to assume a string appending is desired since + is commonly used as a function for this. On the other hand, - is never used for any string operation. Therefore, it's safe to assume that it relates to actual artihmetics and any strings should therefore be converted to numerical values.

This is an issue with untyped languages. If you don't like it, use typescript. End of story.

If you mix types like that, it's your own fault

Lets fix it. I think that since we are removing the ones, then "11" - 1 should be equal to "".

That is just the tip of the iceberg:

You have some random QA Testers to thank for that!

Javascript is a dogshit language that everyone is stuck with. The best that we can hope for is the likes of typescript take the edge off of it. Even though it's like smearing marzipan over a turd. At least it's ok if you don't take a deep bite.

Feels like it could be one of those facebook posts to test "smart" people. Only the top 1% of people can answer this simple math question: "11" + 2 * 2 - 3

Heck, I need to learn some new languages apparently. Here I was expecting an angry "CS0029 cannot implicitly convert type 'string' to 'int'!

This is my favorite language: GHC Haskell

GHC Haskell:

GHCi> length (2, "foo")
1

It makes sense though

It's not that hard to understand what it is doing and why the decision was made to make it do that. JavaScript has a particular purpose and it's mission is not consistency.

It's not like TypeScript doesn't exist if you just get lightheaded at the idea of learning JavaScript's quirks and mastering using it despite them.

Oh we've hit an issue that's solved by another language or we could make another framework

If you're consciously and intentionally using JavaScript like that, I don't want to be friends with you.

It's because + is two different operators and overloads based on the type to the left, while - is only a numeric operator and coerces left and right operands to numeric. But frankly if you're still using + for math or string concatenation in 2025, you're doing it wrong.
