The PHP-based Calculator
While this is more lines of code by the nature of form validation/santization, it was a much easier project. My familiarity with PHP as a result of the CS-008 course material prepared me for setting up the form and doing the arithmatic expressions and logic gates. It was interesting to compare the overlap of PHP and JavaScript variable naming, with the differences of their gates and syntax.
The JavaScript-based Calculator
This presented an interesting challenge, as I learned Javascript last night. I do not believe I have mastered JavaScript yet, however for optional material, I have become proficient enough to perform basic operations. Reformatting the UI to be a more traditional calculator is more of a CSS project than a JavaScript one.
