if case 1 and case 6 - console.log(account eligible); break
default - console.log(account not eligible);

kindly comment each step so to better understand of how things are working together, thanks

Answer 1

const account = '123456abc';
const regex = /[^1-6]/; //using regex to check if the string contains an element 1-6.

if (regex.test(account)) { //this checks if the string contains a number that is not 1-6.
console.log('Not eligible');
} else {
console.log('Eligible');
}

Now change the account by the string you want. Hope this helps.
