I have a JavaScript object. Is there a built-in or accepted best practice way to get the length of this object? const myObject = new Object(); myObject[&quot;firstname&quot;] = &quot;Gareth&quot;; myObject[&quot;lastname&quot;] = &quot;Simpson&quot;; myObject[&quot;age&quot;] = 21;

Are there any JavaScript or jQuery APIs or methods to get the dimensions of an image on the page?

How do I enumerate the properties of a JavaScript object?  I actually want to list all the defined variables and their values, but I've learned that defining a variable actually creates a property of the window object.

I would like to make object from a child so i can edit it, there is a way to do this? I use the Duplication to a sphere from a plane, i want to make object from the result (the new sphere created).  sorry for my english i will put a screenshot for help, i read i have to select the parent and do Shift + Ctrl + A     but its not working. Thanks :)

What's the fastest way to count the number of keys/properties of an object?  It it possible to do this without iterating over the object?  i.e. without doing  var count = 0; for (k in myobj) if (myobj.hasOwnProperty(k)) count++;   (Firefox did provide a magic __count__ property, but this was removed somewhere around version 4.)

Specifically, with a SortedMap&lt;Vector&lt;String&gt;, int&gt; I get "dimensions expected after this (int) token." Help!

Is there a cheap way to get the dimensions of an image (jpg, png, ...)? Preferably, I would like to achieve this using only the standard class library (because of hosting restrictions). I know that it should be relatively easy to read the image header and parse it myself, but it seems that something like this should be already there. Also, I’ve verified that the following piece of code reads the entire image (which I don’t want):  using System; using System.Drawing;  namespace Test {     class Program     {         static void Main(string[] args)         {             Image img = new Bitmap("test.png");             System.Console.WriteLine(img.Width + " x " + img.Height);         }     } }

I'm trying to get the bounds of an object and put a box around it.  Sounds simple right? I just encapsulate all the bounds together and use its center and size to do so.  But the problem is one corner of the box is always at the center of the scene, like a part of the object is there, unless the center of the scene is in the bounds.  This is when object is at the center   This is when it isn't  This is the code i'm using:      public static Bounds Calculate(Transform TheObject)     {         Renderer renderer = TheObject.GetComponent&lt;Renderer&gt;();         Bounds combinedBounds = new Bounds();         if (renderer != null)             combinedBounds = renderer.bounds;         var renderers = TheObject.GetComponentsInChildren&lt;Renderer&gt;();         foreach (Renderer render in renderers)         {             if (render != renderer) combinedBounds.Encapsulate(render.bounds);         }         return combinedBounds;     }

Is the memory space consumed by one object with 100 attributes the same as that of 100 objects, with one attribute each?  How much memory is allocated for an object? How much additional space is used when adding an attribute?

A lot of people have asked if we can measure the distance of an object in photo. But I was wondering if we can measure the size of an object in photo. Of course assuming we know everything from sensor size to height of the photographer etc.  Example: If I take a photo of a bird in flight with only sky as background, there would be no objects in the frame to give an idea of size of the bird. So if I could calculate the size to some approximate level, it would be really nice to know.

I'm looking for a way to have two separate objects be connected, so that when I move the first object the second one will move also. The term parent is used, but how do I parent a object?

While googling, I see that using  can be slow.  has a  method that is available as well.  Is there an efficient way in java to get the file size?

I pulled a repeating pattern from someone else's PSD. Is there a way to figure out the size of the original pattern? I need to create an image with only one tile.

How do I list all the files in a directory and their recursive file sizes?  ---edit  I want to see the sizes 'rolled up' to the parent directories in the directory listed. I don't want to see the child directories or their contents or sizes.

I have an object, and I want to list all the selectors to which it responds. It feels like this should be perfectly possible, but I'm having trouble finding the APIs.

How can I find out the size of a file I opened with an application written in C ?  I would like to know the size, because I want to put the content of the loaded file into a string, which I allocate using malloc(). Just writing malloc(10000*sizeof(char)); is IMHO a bad idea.

Given a Python object of any kind, is there an easy way to get the list of all methods that this object has?  Or,  if this is not possible, is there at least an easy way to check if it has a particular method other than simply checking if an error occurs when the method is called?
