### Check for palindrome
|
|
|
|
Convert string `toLowerCase()` and use `replace()` to remove non-alphanumeric characters from it.
|
|
Then, `split('')` into individual characters, `reverse()`, `join('')` and compare to the original, unreversed string, after converting it `tolowerCase()`.
|
|
|
|
```js
|
|
const palindrome = str => {
|
|
const s = str.toLowerCase().replace(/[\W_]/g,'');
|
|
return s === s.split('').reverse().join('');
|
|
}
|
|
// palindrome('taco cat') -> true
|
|
```
