How to access a element in JavaScript array?

Question

I have a JS array:

a = ["a",["b","c"]]

How I can access string "b" in this array? Thank you very much!

Answer 1

You index into an array like this:

a[1][0]

Arrays are accessed using their integer indexes. Since this is an array inside an array, you use [1] to access the inner array, then get the first item in that array with [0].
