@cschanaj Is there a reason to prefer " over '? Same issue exists in the extension itself. Both are used without any consistency.

this directory use prettier as the preferred linter (a choice from its original author). I just follow his practices. You're right, single quote should used as per #16029 (comment)

@Hainish would you be interested in looking into this, possibly before the next ruleset release?

I've reviewed and made a few changes here: #18062

@cschanaj please review my changes and make sure the clarifications are actually accurate. Otherwise, good to merge. Great work, and thanks for this!
