Mootools convert Hash to array

I have Hash obj: 


var obj = {a,b,c,...};
obj = $H(obj);
I need to convert it to simple array 

[a,b,c,..]
How can I do? Thx.

Object.getValues(myObject) to get an Array of all values.

Object.getKeys(myObject) to get an Array of keys.

For 1.2 simply, Hash provides the same methods.

And don't use Objects {} to store lists like in your example. Arrays are for lists, Objects are for associative arrays.

EDIT:
Since version 1.3 Object.getValues and Object.getKeys has been deprecated and replaced by Object.keys resp Object.values.

since you use $H I am assuming older ver of mootools, 1.2.x since it got deprecated in 1.3 in favour of the new Object. construct

The hash had a .each method:

var Hobj = $H({
    tool: "bar",
    ghost: "goblin"
});

var arr = [];

Hobj.each(function(value, key) {
    arr.push(value); // what to do with key?
});

console.log(arr);

an alternative that grabs the complete objects with their keys but not as array keys:

Hobj.each(function(value, key) {
    var obj = {};
    obj[key] = value;
    arr.push(obj);
});

Assuming you want the values in the array:

var arr = [];
for(var prop in obj){
    if(obj.hasOwnProperty(prop)){
        arr.push(obj[prop]);
    }
}

If you want the property names to be in the array:

var arr = [];
for(var prop in obj){
    if(obj.hasOwnProperty(prop)){
        arr.push(prop);
    }
}

the hasOwnProperty call is important because it will filter out inherited functions and private members of the mooTools hash class that you don't probably want in your resulting array
