Whether you are writing web applications through ASP.NET or designing UWP applications, Vs2019 is a powerful tool that can help you write powerful JS code. This article will briefly introduce how to write JavaScript code using Visual Studio 2019.

1. Create a JavaScript Project

To start writing JavaScript code, you first need to create a project in Visual Studio 2019. Open Visual Studio 2019 and select Create New Project. In the New Project window, select the JavaScript category, and then select Blank Node.js Web Application. Click Next and give the project a name. Click the "Finish" button to create the project.

2. Writing JavaScript Code

Now that the JavaScript project has been created, it’s time to write the code. In Visual Studio 2019, you can create new JS files using JavaScript file templates, which save time by providing some initial code and comments.

Add a JavaScript file to the open project. Right-click on the project and select "Add" -> "New Item". In the "New Project" window, select the "JavaScript File" template and name it. Click "Add" to create a new file.

console.log('Hello world!');
