Now we will consider the logical operations. Logical operations are used between two boolean values.

# Logical operators
There are 3 logical operators:

- AND (`&&`);
- OR (`||`);
- NOT (`!`). 

### AND
The AND (`&&`) logical operator returns `true` if two values equal `true`:

console.log(true && true);
console.log(true && false);
console.log(false && true);
console.log(false && false);

The AND (`&&`) operator requires that all values be `true` in order to return `true`.

### OR
The OR (`||`) logical operator returns `true` if at least one value is `true`:

console.log(true || true);
console.log(true || false);
console.log(false || true);
console.log(false || false);

### NOT
The NOT (`!`) operator inverts the value: not `true` is `false`; not `false` is `true`:

# Using
Logical operations are used to combine some conditions. If you need to check that two values are greater than 4 (or 1), you should use the AND (`&&`) operator:

let a = 5, b = 3;

console.log(a > 4 && b > 4);
console.log(a > 1 && b > 1);

# Priority
Logical operations execute after comparison operations and comparison operations execute after math operations.

> Similar to other operations, you can use parentheses `()` to increase the priority of execution.

First, let's get acquainted with JavaScript and look at its syntax. In this section, you will get a basic familiarity with the JavaScript syntax to make it easier to learn in detail later on.

Now it's time to learn about the data types that JavaScript works with. We'll start by looking at the difference between literals and variables, and then delve into the various data types.

We have become familiar with the various data types. Now, let's learn how to work with them by learning the operations we can perform with each data type.

Next, we will learn how to control the flow of execution. It's a straightforward process: we can tell the interpreter exactly what to do under certain conditions.

Next, we will explore how to shorten code using repetitive looped actions. We will examine the types of loops available in JavaScript and learn how to work with them.

Finally, to be able to write simple programs, we need to learn about functions that can make our lives much easier. We will learn how to create and use our functions.
