I've tried looking to see if this is possible, but I can't find my answer.
I'm trying to get the following to work:
var defaults = { 'background-color': '#000', color: '#fff', weekdays: {['sun','mon','tue','wed','thu','fri','sat']} }; It just gives an error, and I've tried using ({...}) and [{...}] I'd like to be able to access the weekdays using something like:
defaults.weekdays[0]; is this possible?

You can use Array inside object JavaScript. Not even Array anything inside JavaScript objects, including other objects, functions, etc can define. Array is an object, and you can have an object as a property of another object.
Each variable or object in an array is called an element. Unlike stricter languages, such as Java, you can store a mixture of data types in a single array. For example, you could have array with the following four elements: an integer, a window object, a string and a button object.
Syntax: Class_Name obj[ ]= new Class_Name[Array_Length]; For example, if you have a class Student, and we want to declare and instantiate an array of Student objects with two objects/object references then it will be written as: Student[ ] studentObjects = new Student[2];
A nested data structure is an array or object which refers to other arrays or objects, i.e. its values are arrays or objects. Such structures can be accessed by consecutively applying dot or bracket notation.
Kill the braces.
var defaults = { backgroundcolor: '#000', color: '#fff', weekdays: ['sun','mon','tue','wed','thu','fri','sat'] }; 
// define var foo = { bar: ['foo', 'bar', 'baz'] }; // access foo.bar[2]; // will give you 'baz' If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
