But if we're handling capitals and spaces, how about:
let p=s=>(t=>[...t].reverse().join("")==t)(s.toLowerCase().replace(/\s/g,""))
Here,
p("Taco cat") //returns true, p("Arara") //returns true
Another slight mod and we can ignore all non-letter chars (numbers, punctuation, etc.):
let p=s=>(t=>[...t].reverse().join("")==t)(s.toLowerCase().replace(/[^A-z]/g,"")) p("A man, a plan, a canal: Panama.") // returns true
