I don’t want to get into an Internet argument over pedantry. Linter is often used as a catch-all term for static analysis tools.
Wikipedia defines it as
Lint is the computer science term for a static code analysis tool used to flag programming errors, bugs, stylistic errors and suspicious constructs.
Catching type errors and attribute errors would fit under this description, if you use a different, more precise definition at your workplace, cool, then we just have different definitions for it. The point is that your IDE should automatically detect the errors regardless of what you call it.
FizzyOrange@programming.dev
on 26 Sep 2024 21:48
collapse
In common usage a linter detects code that is legal but likely a mistake, or code that doesn’t follow best practice.
Although static type checkers do fit in that definition, that definition is overly broad and they would not be called a “linter”.
Here is how static type checkers describe themselves:
Pyright is a full-featured, standards-based static type checker for Python.
Mypy is a static type checker for Python.
TypeScript is a strongly typed programming language that builds on JavaScript, giving you better tooling at any scale.
Sorbet is a fast, powerful type checker designed for Ruby.
Here is how linters describe themselves:
Pylint is a static code analyser for Python 2 or 3. … Pylint analyses your code without actually running it. It checks for errors, enforces a coding standard, looks for code smells, and can make suggestions about how the code could be refactored.
(Ok I guess it’s a bit redundant for Pylint to say it is a linter.)
Eslint: The pluggable linting utility for JavaScript and JSX
Clippy: A collection of lints to catch common mistakes and improve your Rust code.
Ruff: An extremely fast Python linter and code formatter, written in Rust.
You get the idea… Linters are heuristic and advisory. Quite different to static type checking.

Yes because you used static type annotations. This thread was about code that doesn’t use static types (or static type annotations/hints).
Nope, don’t need to. WebStorm can even detect nonexistent attributes for objects whose format the back-end decides, and tbh I’m not sure what sort of sorcery it uses.

Yeah IntelliJ does amazingly without type annotations but even it can’t do everything. E.g. if you’re using libraries without type annotations, or if you don’t call functions with every possible type (is your testing that good? No.)
Static types have other benefits anyway so you should use them even if everyone in your team uses IntelliJ.
Yeah, our company has been meaning to transition to them for a while. I started saying Jsdoc comments but people complained about the pollution. Then I said fine, we’ll do TypeScript one day instead.
That one day has yet to come. I don’t actually get to decide much at this company, after all. Aah, technical debt.
