The highlighted red lines in Visual Studio Code

I am facing an issue with some red squiggles in my code:

https://i.sstatic.net/UBmgi.jpg

To address this, I have declared variables like this:

import SearchFilterViewModel = SearchFilter.SearchFilterViewModel;
import SearchResultsViewModel = SearchResults.SearchResultsViewModel;
import AddProductViewModel = AddProduct.AddProductViewModel;
import Validator = Validation.Validator;

module Bindings {
    export class Binder {
        constructor() {
            searchFilterViewModel = new SearchFilterViewModel();
            searchFilterViewModel.errors = ko.validation.group(searchFilterViewModel);
            searchResultsViewModel = new SearchResultsViewModel();
            addProductViewModel = new AddProductViewModel();
            ko.applyBindings(searchFilterViewModel, $("#search-filter-page")[0]);
            ko.applyBindings(searchResultsViewModel, $("#search-results-page")[0]);
            ko.applyBindings(addProductViewModel, $("#add-product-page")[0]);
        }
    }
}

After that, I execute the following code:

$(document).ready(function () {
    //apply bindings
    var binder = new Binder();
}

The code compiles and works as expected. Any suggestions on how to eliminate those red underlines?

Answer №1

To begin, you need to specify the properties (which are public by default) :

module Bindings {
    export class Binder {
        searchFilterViewModel:SearchFilterViewModel;
        constructor() {
            this.searchFilterViewModel = new SearchFilterViewModel();

Answer №2

The code compiles successfully and functions as intended.

However, just because the code generates valid JavaScript does not guarantee that there are no compilation errors present.

If the project is run through tsc, there may be errors that arise during compilation.
