Are JavaScript arrays actually linked lists?

Question

I\'m new to Javascript, and notice that you don\'t need to specify an array\'s size and often see people dynamically creating arrays one element at time. This would be a hug

Answer 1

They are actually more like custom objects that use the properties as indexes. Example:

var a = { "1": 1, "2": 2};
a.length = 2;
for(var i=0;i

a will behave almost like an array, and you can also call functions from the Array.prototype on it.
