How can I iterate through all elements of a JavaScript object using slice, excluding the first two elements?

Question

How can I iterate through all elements of a JavaScript object using slice, excluding the first two elements?

Is it possible to loop through all objects in an object, excluding the first two, without creating a new object? I have tried using slice but it only works on arrays.

This is what my object looks like:

{
    First: { },
    Second: { },
    Third: { }
}

Although my JavaScript skills are not advanced, I recommend checking out the following URLs for some guidance:

How to loop through a plain JavaScript object with the objects as members?

These resources may provide you with some ideas on how to approach your problem.

How can I slice an object in Javascript?

If you still haven't found a solution, try implementing a function that iterates over objects based on my suggestion.

Start by creating a variable =1 and follow the logic provided:

If var_inc==1 or var == 2, continue; else, proceed with your tasks.

Next, use a for loop to iterate over objects and apply the previously defined function.

By understanding the logic behind this process, you may find your solution.

When it comes to JS objects, they do not maintain the order of elements as arrays do. In most cases, there is no specific order for key-value pairs within an object. However, you can still access object values by utilizing certain utility libraries (such as underscore https://underscorejs.org/#pairs) or by directly using JavaScript like this:

// This code snippet converts your object into an array of values without maintaining any fixed order
Object.keys(obj).map(key => obj[key])

// This code snippet sorts keys alphabetically before mapping
Object.keys(obj).sort().map(key => obj[key])

It's important to note that while some browsers may preserve key order during a call to Object.keys(), it is not something you should rely on as it is not guaranteed. One way to ensure order is by using an array of objects like so:

[{ key: "First", value: 1 }, { key: "Second", value: 2 }]

To remove specific properties from objects, you can utilize the delete keyword.

delete Obj['A']
delete Obj['B']`

Using these commands will eliminate 'A' and 'B' keys, leaving only the 'C' key in the object.
