Selecting a value in an array in an array; Javascript

Question

I have an array, that happens to be filled with arrays: [[1, "thing"], [2, "other thing"], [3, "still other thing"]] I want to be able to select a value inside one of the arrays without having to make the array a temporary variable and then pick the item. Can this be done?

Answer 1

You can index into a nested array with the same '[]' syntax.

var arr = [[1, "thing"], [2, "other thing"], [3, "still other thing"]];
console.log(arr[0]); // [1, "thing"]
console.log(arr[0][0]); // 1
