+## Why Did We Choose The JavaScript Language?
 
 For this book, we chose **JavaScript**, because it is a **modern** language for high-level programming and at the same time it is easy to learn and suitable for **beginners**. As a use **JavaScript** is **widespread**, with a well-developed ecosystem, numerous libraries, and technological frameworks, and therefore gives many **prospects** for development. **JavaScript** combines the paradigms of procedural, functional, and object-oriented programming in a modern way with easy-to-use syntax. In the book, we'll use the **JavaScript language** and the **Visual Studio Code** development environment, which is available for free from Microsoft.

 So far, we were introduced to various types of loops, learning what structures they have and how they are applied. Now, we need to understand what an **infinite loop** is, when it occurs, and how we can break it using the **`break`** operator.

 Now since we know what the **nested loops** are and how the **`break`** operator works, it is time to figure out how they work together. To get a better idea, we should write a **function** step by step, that should make all possible combinations of **number pairs**. The first number in the pair is increasing from 1 to 3, while the second one is decreasing from 3 to 1. Our solution must continue running until **`i + j`** **is not** equal to 2 (i.e. **`i = 1`** and **`j = 1`**).

 Up to this point, we have viewed functions that do a specific task. For example printing a text, number, or a figure on the console. There is another type of function that can **return** a **result** from their task. We can return a result of the multiplication of two numbers. We will look at this type of function in this part.
 
-### Operator Return
+### The Operator `return`
 To get a result from a function we use the operator **`return`**. He must be **used inside the body** of a function. The **`return`** will tell the program to **stop the execution** of the function and **return** a corresponding value. This value is defined after the **`return`** word. 
 
 In the example underneath we have a **function** that gets the first and last name as **parameters**. Then it combines them and returns the full name.
