Question 6: What is the difference between synchronous and asynchronous code?

Synchronous code is a type of code that is executed in a sequential order, one line at a time. In other words, the next line of code won’t execute until the current line has finished executing.

This type of code is often used in simpler, smaller applications where there is no need for the application to run multiple tasks at the same time. For example, consider the following synchronous code:

function printNumbers() {
  console.log(1);
  console.log(2);
  console.log(3);
}

printNumbers();
