Constant values used to set script ordering in the AddScript overloads that have an order parameter. Callers to AddScript can also use an integer value, these values are provided for convenience. Scripts added using M:Nucleus.ViewFeatures.HtmlHelpers.AddScriptHtmlHelper.AddScript(Microsoft.AspNetCore.Http.HttpContext,System.String,System.Boolean,System.Boolean,System.Int32,System.String) can have the same value in the order parameter as another script, in this case they are ordered by which order AddScript was called in.
