I am currently working on a project using React TypeScript, and I have been utilizing Prettier to help me format the code. Within my TS files, I have several interfaces that utilize Array<T>, but I would like to reformat it to T[].
Is there a way for me to achieve this?
This particular topic falls outside the purview of Prettier and is more within the domain of eslint.
Interestingly, the @typescript-eslint/eslint-plugin actually has a pre-existing rule for this exact issue called array-type. Check it out here: .
The rule states that the following code is incorrect:
const x: Array<string> = ['a', 'b'];
const y: ReadonlyArray<string> = ['a', 'b'];
And on the other hand, deems the following code as correct:
const x: string[] = ['a', 'b'];
const y: readonly string[] = ['a', 'b'];
