How to do JavaScript development on VS

Apr 21, 2023 am 09:11 AM

VS is a very popular integrated development environment. Many developers hope to be able to write JavaScript when using VS. So how to develop JavaScript on VS?

  1. Create JavaScript project

In VS, we can choose to create a blank JavaScript project. Select "New Project" in the left menu bar, then select "ASP.NET Web Application" in "Web", select "Empty" in the project type and check "Add Folder and Core references for:" and " Add Unit Tests project" so that the tests can be automatically run after the code is written.

  1. Writing JavaScript code

VS has a built-in simple JavaScript editor, which can be opened and viewed through the "Solution Explorer" in the "View" menu bar. Add a JavaScript file in it (with a .js extension) and start writing code. It should be noted that formatting is required when writing JavaScript in VS, otherwise the code structure may be very confusing.

  1. Debugging JavaScript code

In VS, you can debug JavaScript code by setting breakpoints. Set a breakpoint by clicking in the empty space to the left of a line of code in the editor. Then use "F5" to start the debugger, VS will automatically run your code and stop when the breakpoint is reached. Then use the various tools in the debugger to view variable values, call stacks and other information to easily troubleshoot problems.

  1. Recommendation

When developing JavaScript, it is recommended to use VSCode instead of VS. VSCode is known as a lightweight editor developed by Microsoft and suitable for JavaScript, TypeScript and Node.js development. It supports syntax highlighting, automatic completion of styles and code snippets, debugging and other functions, which can greatly improve development efficiency.

To summarize, when developing JavaScript in VS, you need to pay attention to code format, use a debugger to troubleshoot problems, etc. If you don't want to use VS, you can choose to use VSCode because it is more suitable for JavaScript development.
