I have an array with the following structure:
[["a"], ["b"], ["c"], ["d"], ...]
How can I turn it into:
["a", "b", "c", "d", ...]
And if there's a way, what's the fastest method of doing it since my array has about 100k elements?
I haven't tried any method yet since I'm a begginer and I've got no idea on how to do it.
