#Rule Details

Enforce consistent usage of type assertions. TypeScript provides two syntaxes for type assertions: as expressions (value as Type) and angle-bracket syntax (<Type>value). This rule enforces a consistent style and can also restrict type assertions on object and array literals.

The assertionStyle option supports "as" (default), "angle-bracket", and "never". Additional options objectLiteralTypeAssertions and arrayLiteralTypeAssertions control whether assertions on literals are allowed.

Examples of incorrect code for this rule (with default "as" option):

const x = <string>value;
const y = <number>42;

Examples of correct code for this rule (with default "as" option):

const x = value as string;
const y = 42 as number;
const z = value as const;
