Load an array from an external txt

If I store an array using a txt file, how can I load it back to jQuery?

Assuming the external txt is

['Parrot', 'Green'], ['Crow', 'Black'], ['Duck', 'White']

How can I load it as

var myArr = [ ['Parrot', 'Green'], ['Crow', 'Black'], ['Duck', 'White'] ];

This is what I've been trying. Does not work.

var myArr;
$.ajax({url: 'files/external.txt'}).done(function(d) {
    myArr = JSON.parse('[' + d + ']');
});

All you need is to change quote and do following -

var strArr = '[["Parrot", "Green"], ["Crow", "Black"], ["Duck", "White"]]';

var finalArr = JSON.parse(strArr);

Your trying to parse 'external' as JSON, but the content does not adhere to the JSON-specification.

Try wrapping all text inside double-quotes instead of single-quotes. 

 //external.json
 [
    [
        "Parrot",
        "Green"
    ],
    [
        "Crow",
        "Black"
    ],
    [
        "Duck",
        "White"
    ]
]

Your code could then look like

$.ajax({url: 'files/external.json'}).done(function(d) {
myArr = JSON.parse(d);
});
