Can you provide access to sample code explained here in this video

Nice. Do you have tips on setting up eslint to not be so aggressive while converting a project across?
Is there a balance between adding 1000 linting rules while still make sure eslint is useful and not a false confidence liability to the overall project?

[@ambientcoder5462]

Good question! It really depends on your project preferences. I’d recommend that you label them as warnings. This allows developers to be aware of the tech debt but also doesn’t prevent them from progressing on immediate work.
