Я создал несколько тестов и хочу создать динамический индикатор прогресса c, поэтому при нажатии кнопки «Завершить» в конце каждого теста он добавляет 20% к индикатору выполнения. Поэтому, когда все 5 тестов пройдены, оно достигает 100%. Тем не менее, я не уверен, как это сделать в jQuery или js, это мой код до сих пор. У меня есть 5 js файлов с одинаковым форматом, просто разные вопросы в массиве, я просто связал один ниже.

<div class="container">

<button class="btn">Answer 2</button>
<button class="btn">Answer 3</button>
