@typescript-eslint/parser eslint jest prettier typescript

eslint-plugin-no-type-assertion

Disallow type assertions in TypeScript code. The rule will forbid both as operator and the angle-bracketed syntax, unless used for const assertions or with the unknown type. The rule also forbids non-null assertions.

The following code becomes invalid:

1const foo: unknown = 42;
2
3const notAString = <string>foo; // can't perform angle-bracketed type assertion
4const alsoNotAString = foo as string; // can't use `as` operator for type assertion
5
6const objectWithOptionalProperty: { a?: number } = {};
7
8const notANumber = objectWithOptionalProperty.a! / 2; // can't use non-null assertion operator
