Using Js.Json.classify

Let's assume that we've validated the following JSON (it's an array of objects):

[  {    "id": 1,    "name": "Christina Langworth",    "address": {      "street": "81 Casey Stravenue",      "city": "Beattyview",      "state": "TX",      "zip": "57918"    },    "phone": "877-549-1362",    "email": "[e-mail]"  },  {    "id": 2,    "name": "Victor Tillman",    "address": {      "street": "2811 Toby Gardens",      "city": "West Enrique",      "state": "NV",      "zip": "40465"    },    "phone": "[phone]",    "email": "[e-mail]"  }]

Now that we have validated the JSON, we're ready to classify it:

switch (Js.Json.classify(validated)) {| Js.Json.JSONArray(array) =>  Belt.Array.map(array, customer => ...)| _ => failwith("Expected an array")};

We pattern-match ...
