+/**
+ * Subscribes to the source, and the observable inputs provided as arguments, and combines their values, by index, into arrays.
+ *
+ * What is meant by "combine by index": The first value from each will be made into a single array, then emitted,
+ * then the second value from each will be combined into a single array and emitted, then the third value
+ * from each will be combined into a single array and emitted, and so on.
+ *
+ * This will continue until it is no longer able to combine values of the same index into an array.
+ *
+ * After the last value from any one completed source is emitted in an array, the resulting observable will complete,
+ * as there is no way to continue "zipping" values together by index.
+ *
+ * Use-cases for this operator are limited. There are memory concerns if one of the streams is emitting
+ * values at a much faster rate than the others. Usage should likely be limited to streams that emit
+ * at a similar pace, or finite streams of known length.
+ *
+ * In many cases, authors want `combineLatestWith` and not `zipWith`.
+ *
+ * @param otherInputs other observable inputs to collate values from.
+ * @return A function that returns an Observable that emits items by index
+ * combined from the source Observable and provided Observables, in form of an
+ * array.
