Short:
let p=s=>![...s].some((c,i,a)=>c!=a[a.length-i-1])
Shorter:
let p=s=>[...s].reverse().join("")==s
In both:
p("potato") //false p("racecar") //true
(First works on palindromic arrays of characters as well as strings, second only on strings)
Nice. Really like the approach with “some” in your first example
