Slide with text: “Rust teams at Google are as productive as ones using Go, and more than twice as productive as teams using C++.”

In small print it says the data is collected over 2022 and 2023.

    1. Look at entire file instead of snippet.
    2. If there is anything that could create a variable x before this area, then that’s where x originates. If not, and if it’s a language where you can create x without using a keyword like let or var, then x is created in the scope in your snippet.

    Types are not necessary at all.

      then x is created in the scope in your snippet

      Saying “x is defined somewhere in the entire program” isn’t satisfactory to many users. Also, you didn’t tell me what type x has. Can I do x + 5?

        1. That isn’t what I said at all. Reread?
        2. Find references / go to definition / rename has absolutely nothing to do with types.

          Find references / go to definition / rename has absolutely nothing to do with types.

          It absolutely does. Without static types an IDE/LSP can’t reliably find all the references / definition and therefore can’t refactor reliably either.

          Consider something like this:

          class Foo:
  bar: int

class Baz:
  bar: str

def a(f: Foo) -> int:
  return f.bar + 1

def b(f: Baz) -> str:
  return f.bar + "1"

          Now imagine you want to rename Foo.bar or find all references to it. Impossible without the type annotations.
