Array Reduction

For the training grade charts for ‘Average Score by Assessment Type’. How did you reduce the type and score array ?

Hi Joydeep,

Thanks for taking this course! To help you solve this problem, you may want to read about unwinding arrays: https://docs.mongodb.com/manual/reference/operator/aggregation/unwind/ Please let me know if you have any further questions.

Best,
Xixi

Hello,

I ran into an issue with my Firefox browser. Firefox displayed the “string accumulate” options, but didn’t always display the “Array Reduction” options. I used Microsoft Edge browser to do the Text Chart lab

Hi John,

I’m not entirely sure this is a browser issue - could you please post a screenshot of your browser view when you try to find the “Array Reduction” option? Thanks!
