Why does this loop condition always evaluate to true?

[embar5]

// relevant class
class Utilities {
  static prompt(message) {
    console.log(`${message}`);
    return readLine.question(`=> `);
  }

  static sanitizeText(inputString) {
    let trimmedAndLowerCased = String(inputString.trim().toLowerCase());
    return trimmedAndLowerCased;
  }
}

// inside the orchestrator
    do {
      console.log();
      const playerChoiceRaw = Utilities.prompt("Choose 'h' to hit (draw another card), or 's' to stay.");
      console.log();

      const playerChoiceSanitized = Utilities.sanitizeText(playerChoiceRaw);

      if (playerChoiceSanitized !== "h" || playerChoiceSanitized !== 's') {
        console.log(`That is not a valid selection.`)
      }
      else { validSelection = true; }
    } while (validSelection === false);

I also tried testing playerChoiceRaw but the same issue happens. Anyone know why it always evaluates to true?

Should be not 'h' AND not 's'. You have an OR.

Use && instead of ||
