LU10.A01 - Hello World

• Work type: Individual
• Timeframe: 15 Minutes
• Means of aid:
  • Only teaching materials, no websearch, no use of ai.
  • Webstorm Codeeditor
• Expected result:
  • A JavaScript program, that displays a greeting on the terminal of Webstorm.

As always, our first program on the server is a small script designed to greet the world with the infamous “Hello World”.

1. Open your Webstorm editor and establish a JavaScriptfile. Name ist helloWorld.js. The file extension is assigned automatically.
2. Write in this script your helloWorld statement, using the JS command console.log(). Save your file.
3. Generate more terminal outputs by using arrays, for iterations and console.log() function. e.g. ['Hello ', 'World!', 'Hello', 'Universe!'];
4. Open a terminal window by clicking the terminal-icon at the left lower rim of Webstorm.
5. Install all missing JS packages, that Webstorm requires from you.
6. Start your server by using the node command, e.g. node helloWorld.js
7. If everything is correct, you will see the helloWorld statement as an output from your server in the bottom terminal window of Webstorm.
