To make the search case-insensitive, let's bring the stirng to lower case and then search:
|
|
|
|
```js run
|
|
function checkSpam(str) {
|
|
let lowerStr = str.toLowerCase();
|
|
|
|
return lowerStr.includes('viagra') || lowerStr.includes('xxx');
|
|
}
|
|
|
|
alert( checkSpam('buy ViAgRA now') );
|
|
alert( checkSpam('free xxxxx') );
|
|
alert( checkSpam("innocent rabbit") );
|
|
```
