Remove all sequentially awaited code

[iamareebjamal]

After removing await from loops, it is time to remove all sequentially awaited code unless result of one call depends on the next.

If there are 4 requests and each take 5 seconds, they can be completed in 5 seconds, but right now they are taking 20 seconds. It's like deliberately making the site slow. Try to reduce multiple awaits in any function to a single await unless the result of an await is required below
