I dint know many OO languages that don’t have a useless toString on string types
Okay, fair enough. Guess I never found about it because I never had to do it… JS also allows for "test string".toString() directly, not sure how it goes in other languages.
It’s also incredibly useful as a failsafe in a helper method where you need the argument to be a string but someone might pass in something that is sort of a string. Lets you be a little more flexible in how your method gets called
Java would be "test string".toString(). C# has "test string".ToString(). Python has str("test string") (as str() is Python’s toString equivalent). Rust has String::from("test string").to_string().
That’s just from the top of my head. I’m sure there’s more.
Edit: actually, I think Rust’s to_string() may not be entirely useless, I think it may be used as a consuming placeholder for clone()? Not sure how that would be useful, but it’s not a complete no-op at least.
