12/26/2023: I built my first JS app. I learned about the script tag and pointed script tag to a src (index.js),about variables (let), learned about numbers and do mathematical operations and increment numbers as well as resetting it back to zero, learned about strings, used console.log, created functions (increment and save functions for buttons on a counter), learned what DOM (document object model) stands for, worked with getElementbyId(), and worked with innerText and textContent.
