extracting the array value from the hash

Question

I have this hash

data = {"05 INTERNAL":[["5e Research","66"]],"06 MISCELLANEOUS":[["6a Internal Training","69"]]}

I want to get the value of the first key in the array. when I do

Object.values(data)[0]

I get an array which consists of

[["5e Research","66"]]

How do I extract the value "66" from this using jquery?

Thanks for the help!

That's not a hash it's a map. A "hashMap" is one particular way to implement a map, but not all maps are hashmaps. (...) and what's with [["5e Research","66"]] - that is an Array with one element: an Array of two strings. Why not just a single level ["5e Research","66"] ? — Stephen P

You can reference a property with string, like that:

const data = {
  "05 INTERNAL": [
    ["5e Research", "66"]
  ],
  "06 MISCELLANEOUS": [
    ["6a Internal Training", "69"]
  ]
}

console.log(data['05 INTERNAL'][0][1])

var data = {"05 INTERNAL":[["5e Research","66"]],"06 MISCELLANEOUS":[["6a Internal Training","69"]]};

The answer is:

data['05 INTERNAL'][0][1];
