I have such a task, please help with the solution!
There are graph nodes which have objects.
Please help me find the average value of the 'val' fields and the node with the minimum value of the 'val' field



Example graph structure(graph tree) Also i need implement this on JavaScript. Thank You very Match

You could create recursive function with for...in loop and first calculate total sum and total number of nodes and then use those 2 values to calculate average.
