javascript: object property is array, but append isn't working

Question

var objs = {
   'prop': []
}
objs['prop'].append('q');

Error: TypeError: objs.prop.append is not a function

Why this code is not working ?
Why console.log(typeof(objs['prop'])); is object not array ?

typeof is a red herring. (typeof new Array()) = "object" in Javascript. — Elliot Nelson

var objs = {
   'prop': []
}
objs['prop'].append('q');

should be:

var objs = {
   'prop': []
}
objs['prop'].push('q');

Because there are no associative arrays in JavaScript, an associative array is actually an Object. Nothing more nothing less.

Don't know how this is related to the question.

@JaredPar It is an answer to the second question, about why typeof an array returns "object"
