 Elena is the new quality manager of a newspaper factory. As she has just arrived in the company, she has decided to review some of the processes in the factory to see what could be improved. She found out that technicians are doing a lot of quality checks by hand. She sees there is a good oportunity for automation and asks you, a freelance developer, to develop a piece of software to monitor some of the machines.

+# Introduction
+
 Errors are useful to report when something is wrong or unexpected in a program or a piece of code.
 
 They are javascript objects.
 
 The main property of this object is `message`:
 
 ```javascript
-const error = new Error('Oops, something went wrong')
+const error = new Error('Oops, something went wrong');
 
-console.log(error.message)
+console.log(error.message);
 // => "Oops, something went wrong"
 ```
 
 Using the `throw` syntax, you can throw an Error.
 
 ```javascript
-throw new Error('Oops')
+throw new Error('Oops');
 ```
 
 When an Error is thrown, the current execution is stopped and resume in the first catch block of the call stack.
 
 ```javascript
 try {
-  throw new Error('Oops')
+  throw new Error('Oops');
 } catch (error) {
-  console.log(error.message)
+  console.log(error.message);
   // => "Oops"
 }
 ```
