JS Calculator
Introduction¶
Now that you have learned JavaScript syntax and been given an introduction to how JavaScript is used in the browser, it is time to apply your skills and get some experience creating a user interface.
Overview¶
You will create a calculator with JavaScript. The HTML for the calculator's necessary parts has been provided to you in the index.html file. You are adding code to the public/calc.js file that will dictate the functionality associated with a calculator.
