Throttle Stream

Node.jsStreamsThrottle

Given input events [time, value], emit at most one event per window ms.
Always emit the first event. Subsequent events within the window are dropped.

solve(window, events) returns the emitted values in order.

Output: ["a","c"]
Test #2Both pass
Input: [100,[[0,"a"],[200,"b"]]]
Output: ["a","b"]
Test #3Empty
Input: [50,[]]
Output: []
Test #4Half emitted
Input: [10,[[0,1],[5,2],[10,3],[15,4]]]
