Number one this week, Financial is a library written in TypeScript to perform elementary financial operations about payments and interest rates.
Speaking of calculations, x-spreadsheet is a library to include a spreadsheet in a web page, using a <canvas> element, to get something similar to Google Sheets for example.
The features include:
- basic “formulas”: sum, average, concat…
- undo / redo
- copy-paste of range of cells
- formatting options
If you need a spreadsheet in your web page, check the other contenders on Best of JS like SheetJS or jExcel that we mentioned one year ago in a previous issue.
