A Windows script is a text file. You can create a script with any text editor as long as you save your script with a WSH-compatible script extension (.js, vbs, or .wsf).
The most commonly available text editor is already installed on your computer Notepad. You can also use your favorite HTML editor, Microsoft Visual C++, or Visual InterDev.
To create a script with Notepad
WScript.Echo("Hello World!");
Hello.js
