how to write an array literal notation in JS?

Question

var myArray = new Array();
myArray.prop = 'test';

i've already tried this, but it logs undefined value.

var myArray = [prop='test'];
console.log(myArray.prop);

Please take a tour of the basics first https://developer.mozilla.org/en-US/docs/Web/JavaScript — elclanrs, Oct 12 '13 at 05:44

The array literal is:

['foo', 'bar', 'baz']

You cannot use keys in this, because Javascript arrays do not have string keys. They're numerically indexed lists. Setting a property on an array object does not do what you think it does.

What you're looking for is an object literal:

{ foo : 'bar', baz : 42 }

Unless that's an example of what not to do/unexpected results, you should not follow that tutorial/site/whateverthatisfrom anymore. – deceze Oct 12 '13 at 06:25

Arrays in JavaScript cannot have string indices... they must be numbers. What you're looking for in your case is an object.

var myObject = {
    prop: 'test'
}
