const reverseStr = s => [...s].reverse().join("") console.log(reverseStr("Lorem ipsum dolor sit amet!"))const reverseStr = str => Array.from(str).reverse().join("")- const reverseStr = s => [...s].reverse().join("")
console.log(reverseStr('hello world'));- console.log(reverseStr("Lorem ipsum dolor sit amet!"))
