 In this **current** chapter, we are going to examine **nested conditional statements** in the **JavaScript** language, by which our program can execute **conditions**, that contain other **nested conditional statements**. We call them **"nested"** because **we put the `if` condition** into **another `if` condition**. We are going to examine the **more complex logical conditions** through proper examples.
 
-## Nested conditions
+## Nested Conditions
 
 Pretty often the program logic requires the use of **`if`** or **`if-else`** statements, which are contained one inside another. They are called **nested** **`if`** or **`if-else`** statements. As implied by the title **"nested"**,these are **`if`** or **`if-else`** statements, that are placed inside other **`if`** or  **`else`** statements.

-We should notice that the **output** of the program **depends on few things**. First, we have to check what **gender** entered and then to check the **age**. Respectively, we are going to use **a few** **`if-else`** blocks. These blocks will be **nested**, i.e. from the **result** of the first, we are going to **define** which of the **others** to execute.

+### How Does The && Operator Work?
 
 The operator **`&&`** accepts **a couple of Boolean** (conditional) statements, which have a **`true`** or **`false`** value, and returns **one** boolean statement as a **result**. Using it **instead** of a couple of nested **`if`** blocks, makes the code **more readable**, **ordered**, and **easy** to maintain. But how does it **work**, when we put a **few** conditions one after another? As we saw above, the logical **"AND"** returns **`true`**, **only** when it accepts as **arguments statements** with the value **`true`**. Respectively, when we have a **sequence** of arguments, the logical "**AND**" checks either until one of the arguments is **over**, or until it **meets** an argument with value **`false`**.

 The program will run in the **following** way: **It starts** the check from **`a`**, **reads** it, and accepts that it has a **`true`** value, after that, it  **checks `b`**. After it has **accepted**, that **`a`** and **`b`** return value **`true`**, **it checks the next** argument. It gets to **`c`** and sees that the variable has a **`false`** value. After the program accepts that argument **`c`** has a **`false`** value, it calculates the expression **to `c`**, **regardless** of what the value of **`d`** is. That is why the evaluation of **`d`**is being **skipped** and the whole expression is calculated as **`false`**.

 We have already learned what the logical **"OR"** **represents**. But how is it being achieved? Just like the logical **"AND"**, the program **checks** from left to right **the arguments**, that are given. To obtain **`true`** from the expression, just one argument must have a **`true`** value, respectively the checking **continues** until an **argument** with **such** value is met or until the arguments **are over**.
