JavaScript is an essential language in web front-end development, and Visual Studio (hereinafter referred to as VS) is a powerful development tool from Microsoft. VS not only supports development in multiple languages, but also provides many convenient functions to allow us to write code more efficiently. In this article, we will introduce how to write JavaScript code using VS.
1. Download and install VS
First, you need to download and install Visual Studio. You can download the latest version of Visual Studio from the Microsoft official website, or use the community edition for development. The community edition is free.
2. Create a new project
After starting VS, select "New Project", select the "HTML/JavaScript" template, and then select the JavaScript project, as shown in the following figure:
After naming your project and determining the save path, you can create your new project.
3. Writing Code
Visual Studio provides many convenient functions to make us more efficient when writing JavaScript code. For example, automatic code formatting, code trimming, find and replace and other functions.
Like many other tools, VS also supports code highlighting and syntax highlighting. This makes it easier for us to read our own code, and we can see syntax errors and warnings immediately, as shown in the figure below:
In addition, VS also supports Intelligent Sense, This is also one of the most needed features when writing JavaScript code. When we type code, VS will automatically pop up the code completion menu, as shown in the following figure:
Similarly, VS also supports find and replace functions, which allows us to quickly Modify or find specific text in code.
4. Debugging code
Debugging is an important part of writing code. VS provides several useful debugging functions that allow us to easily find and fix errors in the code. .
When debugging the page, we can use the "Debug" window to view the running status of the current code, including assigned variable values and the current call stack. In addition, we can also set breakpoints in the "Debug" window so that the code stops running when it reaches a specific line, as shown in the following figure:
VS also supports debugging IntelliSense for JavaScript code, which makes it easier to check for syntax errors and other errors. If you encounter an error, you can view the error message in the "Debug" window, as shown below:
5. Summary
In this article , we introduced how to use VS to write JavaScript code. VS provides many important functions, such as code highlighting, intelligent sensing, debugging, etc., allowing us to write code more efficiently and detect code errors. If you are a front-end developer and want to write efficient JavaScript code, VS will be a powerful tool for you.
