Remove underscores in Vscode (image 1 = problem, image 2 = Solution)

Question

How to remove these underscores that make it difficult to read code in my Vscode.

Answer 1

This type of "Warning" exists for several languages and for different situations, it can be an error, or an alert or just an unrecognized experimental attribute.

You can try putting in JSON of their setting so, since the problem is in JS.

{
    "compilerOptions": {
        "experimentalDecorators": true,
        "allowJs": true
    }
}

If it doesn’t work, a "gambiarra" would put all the decorations alert with transparent color, so they are invisible on the screen...

{
    "workbench.colorCustomizations": {
        "editorError.foreground":   "#00000000",
        "editorWarning.foreground": "#00000000",
        "editorInfo.foreground":    "#00000000"
    }
}
