Javascript Calculator

A simple responsive calculator written in vanilla Javascript. It can be viewed here: https://branderso87.github.io/calculator/

Triumphs:

The front end was easy to assemble using the mockup provided and a bit of flexbox.

Problems:

This was my first attempt to do a project completely in Javascript. Functionally, it turned out ok but I had issues with:

  • Event handlers on each of the keys
  • How to convert concatenated numbers and strings to an operation
  • Handling multiple number entries
  • Error handling (mostly because THERE IS NO ERROR HANDLING)
  • Testing
