When I format TypeScript files using Prettier, it consistently removes the brackets as shown in the following scenario:
private requestFilterHooks: Dict<(...args: any[]) => (Promise<void> | void)> = {};
This code snippet will be converted to:
private requestFilterHooks: Dict<(...args: any[]) => Promise<void> | void> = {};
In function types, parentheses are omitted to align with the precedence rules of function expressions, ensuring consistency between type declarations and value representations.
Version 2.8.1 of Prettier Access playground here
Initial Code:
const x = (a) => (b + c);
type X = (a: A) => (B | C);
Resulting Code:
const x = (a) => b + c;
type X = (a: A) => B | C;
It is important to note that removing these parentheses does not alter the code's meaning.
