const includeStatement = { include: matrixList };

We use this script in the following workflow. It has two jobs: `generate-matrix` and `test`. In the `generate-matrix` job, we run the `matrix-script.js` shown above which logs the string to `stdout`. The `::set-output name=matrix::` is a special function within Github Actions which tells the runner to set this as an output value for this step. We assign it to a variable by setting the `id: set-matrix`. Finally, we can set it as an output for the whole job by specifying it in `outputs`.
