+## concatArrayEager
+
+Launches all at once and emits all items from a source before items of the next are emitted.
+
+For example, given two sources, if the first is slow, the items of the second won't be emitted until the first has
+finished emitting its items. This operators allows all sources to generate items in parallel but then still emit those
+items in the order their respective `Flow`s are listed.
+
+Note that each source is consumed in an unbounded manner and thus, depending on the speed of
+the current source and the collector, the operator may retain items longer and may use more memory
+during its execution.
+
