Question

Want to convert this:

[["1", "2", "3"], ["4", "5", "6"]]

to this:

["1", "2", "3"], ["4", "5", "6"]

to be passed into Array.product(), and the first array can contain an unknown number of other arrays. for example, the array given may also be

[["1", "2", "3"], ["4", "5", "6"], ["7", "8", "9"]]

And ultimately, I need to pass the argument as:

otherArray.product(["1", "2", "3"], ["4", "5", "6"], ["7", "8", "9"])

Thanks ahead of time!

Answer 1

otherArray.product(*[["1", "2", "3"], ["4", "5", "6"], ["7", "8", "9"]]);

* is used in argument list to unpack array contents to arguments (like
here) or to pack arguments into an array,like in “def mymethod(*args)”
