Today we’re going to create a fully working Scientific Calculator App with Vanilla JavaScript and HTML.

This a beginners tutorial, And I’m going to discuss the logic behind every line of code first, then once you’re ready and fully understand what we’re going to do, then we can open our text editors,

What you’re going to learn in this tutorial:

• How to select an HTML element in JavaScript using querySelector method.
• How a forEach method works.
