 369 (8)| Cheerio | Avoid recomputing value that will be reused | Repeated execution |
+27a | Chalk | Don't concatenate the arguments into string with slice.join if there is only one argument. In latter case use explicit string concatenation | Inefficient API usage, Generic API, Special cases |
+27b | Chalk | Precomputed style function. Merge multiple return statements to one | Other |
+28 | Chalk | Replace Array.prototype.reduce() with explicit for loop | Inefficient iteration |
