2You have to provide more context. Is this a string you have that you want to turn into an object? Or do you have an object of that form? What exactly do you want to "parse"? It's certainly not JSON. – Felix Kling Mar 23 '17 at 21:35

Parse what exactly? This already looks as much like a JavaScript object/array as it will get. – TimoStaudinger Mar 23 '17 at 21:35

maybe he want to access the array inside – Nicholas Mar 23 '17 at 21:48

Since you are using an invalid identifier as your key (notes[]), you will need to use bracket syntax to access:
var data = { 'notes[]': [ 'book', 'copy', 'pencil', 'eraser' ] };
console.log(data['notes[]']);Probably would be better to name the key notes instead of notes[]. Then you can access with dot notation: data.notes

@zerkms reserved characters is probably not the correct nomenclature, what I mean by that is: "Characters that cannot be used in a variable, property or function name". `data.notes[]` will not work – Rob M. Mar 23 '17 at 21:38

"variable, property or function name" --- or in short, "identifier". So just call it "a not valid identifier" – zerkms Mar 23 '17 at 21:39

Maybe you want like as below code.
var res = { 'notes': [ 'book', 'copy', 'pencil', 'eraser' ] };
console.log(res.notes[0]); //=> book
console.log(res.notes[1]); //=> copy
console.log(res.notes[2]); //=> pencil
console.log(res.notes[3]); //=> eraser
