Javascript - Chrome Console - What does "Array(0)" mean?
That's how Chrome displays an 0-length array in value summaries in the console. Empty arrays can still contain fields due to the nature of JavaScript.
var obj = {};obj.array = [];obj.array.myField = 1;console.log(obj);This will log the following in the console:
> {array: Array(0)}And when I expand it:
{array: Array(0)} array: Array(0) myField: 1 length: 0 __proto__: Array(0) __proto__: ObjectThis shows that named fields are not items in an array.
If you want an associative array (Array with named indexes), you should use plain JavaScript objects.
var obj = {};obj.A = 10;
