What would be the motivation and benefit of converting this project to TypeScript?

[cacieprins]

@MikeMcC399 , just to keep it aligned with most other Cypress repos - this is an icebox issue, or one that may be good for a contributor, but I do not believe it's one that we're going to tackle soon.

Thanks for providing an explanation! This repo probably shouldn't be a candidate for TypeScript conversion until other enhancements have been implemented, such as full conversion to ESLint v9 and removal of support for previous ESLint versions. That would provide a clean base for any conversion.

@MikeMcC399 Thank you for bringing those to my attention!

Before making any decision to migrate the repo to TypeScript, consideration should be given to:

• who will maintain this repo (Cypress.io, community or both)
• additional dependencies necessary for TypeScript and TypeScript linting, such as typescript-eslint
• support by Cypress for TypeScript. Currently the documentation is outdated Typescript for >=v10 cypress-documentation#5262. Other open TypeScript issues for Cypress.

Based on the current status, migrating to TypeScript would introduce additional challenges.

• Export Typescript types declaration #232 relates to this issue

At this time, converting this repo to be TypeScript-based would be disruptive and that is not likely to change in the coming months.

If there are compelling reasons to change this assessment, then this request can be re-opened.
