you can add resources.resx to your project and write the function below in a common controller.

#if !DEBUG
        [OutputCache(Duration = 24 * 60 * 60)]
#endif
        [AllowAnonymous]
        public ActionResult ResourcesForJavascript()
        {
            try
            {
                var resourceSet = JsResources.ResourceManager.GetResourceSet(CultureInfo.CurrentUICulture, true, true);
                var resourceDictionary = resourceSet
                                .Cast<DictionaryEntry>()
                                .ToDictionary(entry => entry.Key.ToString(), entry => entry.Value.ToString());
                var json = JsonConvert.SerializeObject(resourceDictionary);
                var javaScript = $"window.Resources = window.Resources || {{}}; window.Resources.resources = {json};";
                return JavaScript(javaScript);
            }
            catch (Exception ex)
            {
                WebExceptionHelper.FillModelStateOrTempDataWithExceptionMessages(ex, ModelState, TempData);
                return null;
            }
        }

And call it as follows in the _Layout.cshtml

<script type="text/javascript" src="@Url.Action("ResourcesForJavascript", "CommonActions")"></script>

To use resource file message, you need to inject Locatization on related view. Example: assume you have a view with the name abc.cshtml and you want to show an alert message from resource file when a button is clicked

View: abc.cshtml

@using Microsoft.AspNetCore.Mvc.Localization
@inject IViewLocalizer Localizer

in script section

<script type="text/javascript">
function callOnButtonClick(){
alert('@Localizer["Hello message from resource"]');
}
</script>
