Before You File a Proposal Please Confirm You Have Done The Following...
- I havesearched for related issues and found none that match my proposal.
- I have searched thecurrent rule list and found no rules that match my proposal.
- I haveread the FAQ and my problem is not listed.
My proposal is suitable for this project
- My proposal specifically checks TypeScript syntax, or it proposes a check that requires type information to be accurate.
- My proposal is not a "formatting rule"; meaning it does not just enforce how code is formatted (whitespace, brace placement, etc).
- I believe my proposal would be useful to the broader TypeScript community (meaning it is not a niche proposal).
Description
I've seen occasional code authors write code with a.filter returning element[0], perhaps not knowing that.find does the same thing. Perhaps we could write a rule that flags for this, and uses the type system to know whether the collection being.filtered is an array/array-like?
Fail Cases
constvalues=['a','b ','c'];constresult=values.filter(value=>value.includes(' '))[0];
Pass Cases
constvalues=['a','b ','c'];constresult=values.find(value=>value.includes(' '));
