Basic project to convert a number base(10) to a number base(2), in other words, from decimal to binary.
It's a github page, access here:
Just open the file index.html in your browser and follow the instructions there.
I create a new JavaScript file named scripts.js, where I wrote code to convert these numbers, binary or decimal. Just catching the elements by id and making the operation.
It is a project with HTML and JavaScript, without CSS.
