"Matches/is within" as in *contains*? Otherwise what? One of the two arrays is fixed (constant) and you match the other against it? Or, both arrays are dynamic and you need to cross-match them? > const matched = arr1.some(a => arr2.includes(a)); Besides asking sloppy questions, do you use const vs let (vs var, and functions vs lambdas) just randomly? Or is it on purpose to make the code (even more) unreadable? Julio
