Blocking vs Non-blocking Code in Node.js

In this lab, you'll explore the difference between blocking (synchronous) and non-blocking (asynchronous) code in Node.js. You'll create two separate files, one for blocking code and the other for non-blocking code, and write code to read the content of the package.json file. Then, you'll run the code and observe the difference between the two approaches.

When you write and run blocking code, the JavaScript engine waits for the task to complete before moving to the next line of code. On the other hand, non-blocking code allows the JavaScript engine to execute other tasks while waiting for the completion of a task, which leads to better performance in certain scenarios. Node.js heavily relies on non-blocking code and asynchronous functionality due to its single-threaded nature.
