Formulas for Coda

How do we know which formulas and how to proceed with formulas like as Gill did (.status & . count) and what does dot( . ) mean in this lesson

So the . before filter is so that Coda understands that we are initiating a command to run which is the filter command. Without the dot it would just be a normal word. Hope that makes sense.

For status I will try to break it down for you:

Note: By writing the table name coda will automatically allow us to select it.

  1. From the Learning plan table
  2. We are going to .filter() a specific part of the table
  3. Inside the () we write what we want to grab from the table. Which is to grab the status (bear in mind for status we are not adding a . because just like the table we are selecting something and it is not a command) and we want the status to be equal to "In Progress" as an example.
  4. The .count() is there to check how many lessons with the status "In Progress" there are.

So the purpose of writing that code in the video is to display how many lessons we have not started, started or finished. And shows an example of extra customization you can do in coda.
