unicorn/prefer-string-slice Pedantic
What it does
Prefer String#slice() over String#substr() and String#substring().
Why is this bad?
String#substr() and String#substring() are the two lesser known legacy ways to slice a string. It's better to use String#slice() as it's a more popular option with clearer behavior that has a consistent Array counterpart.
