            You can do it with the $event parameter. Make sure to compare your values safely.

            If your value is not in the right type or has spaces or unwanted chars, this c.state == val might not work.

            You can use the trim function to compare your value safely: c.state.trim() == val.trim()

            Nested for loop in nodejs seems to be running asynchronously
            Asked 2020-Feb-16 at 19:52

            So I have two for loops, and one is nested inside another but the results they return seem to be running the first loop and returning its results than the nested loop. How could I make it run in a synchronous behavior? For example, all the topicData gets printed in a row instead of printing one topicData and moving on to the nested for loop. I'm not sure if this is the proper way to implement the async await. Any pointers would be appreciated. Thanks

            There are couple of issues here

            • You are trying to do callback style code in loops while you have promise methods available.
            • You could also do things in parallel using promise.all
            • Because of callback style the code is very complicated
            • You are awaiting where it is not required. For example in the callback

            1) First of all if your data is already stored in files per group id there is no reason to mix it up and then group by id using Spark. It's much more simple and efficient to load for each group id only relevant files

            2) Spark itself parallelizes the computation. So in most cases there is no need for external parallelization. But if you feel that Spark doesn't utilize all resources you can:

            a) if each individual computation takes less than few seconds then task schedulling overhead is comparable to task execution time so it's possible to get a boost by running few tasks in parallel.

            b) computation takes significant amount of time but resources are still underutilized. Then most probably you should increase the number of partitions for your dataset.

            3) If you finally decided to run several tasks in parallel it can be achieved this way:
