Avoiding anys with Linting and TypeScript
anys with Linting and TypeScript · 9 min read
TypeScript's any type is, by design, the single most unsafe part of its type system.
The any type indicates a type that can be anything and can be used in place of any other type.
Using any is unsafe because the type disables many of TypeScript's type-checking features and hampers TypeScript's ability to provide developer assistance.
typescript-eslint includes several lint rules that help prevent unsafe practices around the any type.
These rules flag uses of any or code patterns that sneakily introduce it.
In this blog post, we'll show you those lint rules and several other handy ways to prevent anys from sneaking into your code.
