Adding a Fictitious Pair to a JavaScript Object Literal

When I work with object literals in JavaScript, I often encounter syntax errors when adding a new label / value pair without including the trailing comma. This can be frustrating as it's easy to forget to include the necessary delimiter.

.draggable({
    containment: "parent",
    opacity: 0.50  // <- missing comma
    revert: true   // new pair
});

To simplify this process and avoid mistakes, I've started using a dummy pair at the end of my objects. By doing so, all newly added pairs automatically have the required trailing comma. I'm curious if there are other conventions for addressing this issue. Is using an empty double quote pair smart or silly? Any suggestions would be appreciated. Thank you!

.draggable({
    containment: "parent",
    opacity: 0.50,
    "": null       // dummy pair
});

Nah.

This is just plain old ridiculous.

What you should really do is utilize code quality tools like ESLint and Prettier. By integrating these into your workflow, whether through pre-commit hooks or within your text editor, you'll be able to catch these mistakes before they become a problem.

Or, if you're feeling adventurous, you could always try adopting the coding style of Gordon Ramsay.

const ingredient = { name: "onion"
                    , quantity: 1
                    , chopped: true
                    };

One approach is to start with an object that has no data and then gradually populate it. This method eliminates the need for commas and ensures consistency throughout.

var newObject = {};
newObject.dimension = size;
newObject.color = 'blue';
.draggable(newObject);

When it comes to working with associative arrays, I find myself using them quite frequently, which is why I don't necessarily miss the last comma. If you're looking for ease of use, consider checking out Coffee Script.

Here's an example of what your code would look like:

draggable
  foo:
    key: value
  bar:
    key: value

Upon compilation, it would become:

draggable({
  foo: {
    key: value
  },
  bar: {
    key: value
  }
});
