There are dimmed properties in my settings.json file. Are they dimmed because they are not being used? Can I safely remove them?

Answer: Yes, it is safe to delete settings that have a dimmed-out color. Just to be sure you can check if you have the Git and Prettier extensions installed/uninstalled as it seems those extensions have dimmed-out settings.json file.

Reasoning: Well in your case, and as @j D3V mentioned, you've disabled or uninstalled the git extension. This means that any settings related to or needed by the extension will be dimmed-out and are no longer required.

I was surfing the web and testing out stuff in my VSCode, and I found a setting in my settings.json file that too, was dimmed out:

The dimmed out setting is "color-highlight.markerType": "dot-before",. This is because I no longer have the extension that used this setting, the extension was named 'Color Highlight':

In the image above, you can see I no longer have the installed extension, however, I once did. Basically, the settings are dimmed-out because they were related to an extension you no longer have installed. Thus it is safe to delete them. If you keep the settings, that's perfectly fine too!

I seen this question when you first posted it, but something was odd.

So the Properties that are Dimmed, Should Be interpreted as "Unreachable by the Control-flow"

In other words, the are unnecessary, and VS Code cannot make use of them.

The editor can be configured to change how dim — or "how opaque" — the code that is "unnecessary" renders. Its a theme property that changes the dimness. I included the configuration to use in your settings.json file below.

NOTE: _The setting uses a base-16 color format, much like you often will see in CSS, or SVG, however, it must have an 8 or 4 digit hex-color as to properly set the transparency. If an eight digit number is used, the first 6 digits are ignored, if a 4 digit is used then the first 3 are ignored. Below is an example of a properly configured configuration for changing how dim "Unreachable Code" renders (aka "unnecessary code").

  {
    "workbench.colorCustomizations": {
      "editorUnnecessaryCode.opacity": "#00000080"
    }
  }

Its Important to Know Why Code isn't Being Reached

These types of details should always be obvious, if not, something might be wrong, and it is worth investigating. When I first took a look at the image you included (of your settings.json file) I immediately noticed something was off. There were settings that were part of the core, fundamental features that are built-in to VS Code. The settings are contributed through "built-in extensions". The only way they could be dim, is if you disabled one or more built-in extension.

First Let me state, you should never disable VS Codes core extensions that are built-into the editor. If you do, you can't expect the
