Research the topic of Node.js and understand its purpose and functionality.
Open the command prompt or terminal on your computer.
Navigate to the directory where the Node.js application files are located using the 'cd' command.
Type 'node main' in the command prompt to execute the 'main' file of the Node.js application.
The Node.js runtime environment will interpret and execute the code written in the 'main' file.
The code in the 'main' file may include various functionalities such as importing modules, defining variables, declaring functions, and executing operations.
The Node.js runtime will sequentially execute each line of code in the 'main' file, following the logic and instructions provided.
Any errors or exceptions encountered during the execution of the code will be displayed in the command prompt.
Once the execution of the 'main' file is complete, the Node.js application may produce output or perform specific tasks, depending on the code written.
The command prompt will remain open after the execution, allowing further interaction or running additional commands if needed.
