Answer 1

Hey! If you tried and got stuck, here's the code:
const longestPalindrome = (str) => {
let arr = str
.replace(/ /g,"")
.toLowerCase()
.split("")
arr
.forEach(elem=>{
if([...arr].join("") !== [...arr].reverse().join("")){
arr.splice(0,1)
}
})
return arr.join("")
}

longestPalindrome("I want a Toyota")

Output:
atoyota

Cheers.
