Functions

Charta has a built in programming language. With it you can make selections of or perform manipulations on your data. In the previous example we added a Note to a Weekly task. We will show you some basic techniques to use functions on these notes and tasks. But before we do so, we start with showing you how to evaluate or run functions and help you create a function that doesn't use any data so that you can get acquainted with the different features on a function control.

Prepare for coding

Up till now we have only looked at the data part within the demo. Now we are going to add functionality. To be able to get into the code you have to press Alt+d. This gets the application into developer mode.

Function evaluation
