Next steps / TODO

• More tests - check the display value from the DOM
• Handle key presses as well as clicks
• Some key errors not handled e.g. '.' after an operator
• Some operations not handled adding and multiplication of negative numbers e.g. 2*-9
• Mobile optimised display
• More operators e.g. %, √
• Improve button positioning e.g. move all operators to the right
• Improve button styling e.g. larger '=' and colour operators differently
• Custom favicon
• Swap out calculateResult.tsx hook logic for 3rd part library or vanilla javascript to fix security issue, make more robust, add new features
