filter and regex issue

Issue

I want to filter an array with a function.

if (this.pendingItems.customer?.emailAddresses) {
  this.pendingItems.customer.emailAddresses.filter(email => {
    isEmailValid(email);
  });
}

the function isEmailValid()

export function isEmailValid(s: string): boolean {
  const re =
    /^[a-z0-9+-][a-z0-9_+-]*(\.[a-z0-9_+-]+)*@([a-z0-9-]+\.)+[a-z0-9-]{2,}$/i;
  return re.test(s);
}

return the correct response (true or false) with the emails(test@email.com and test2email) I pass it, but the filter don't work.

Solution

So the solution was:

if (this.pendingItems.customer?.emailAddresses) {
  this.pendingItems.customer.emailAddresses = this.pendingItems.customer.emailAddresses.filter(isEmailValid);
}

I forgot to reassign the variable ;p
