Summary  
This chapter explains boolean logic operators (AND, OR, NOT) for combining and inverting conditions in code, demonstrates their truth tables, and highlights operator precedence rules.

General domain of usage  
Conditional control flow

Now, let's explore logical operations. Logical operations are used to manipulate and make decisions based on boolean values.

# Logical Operators
There are three logical operators in JavaScript:

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

### AND (&&) 
The AND (`&&`) logical operator returns `true` only when both values it operates on are `true`. The result is `false` if any value is `false`.

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

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

### OR (||)
The OR (`||`) logical operator returns `true` if at least one of the values is `true`. It returns `false` only when both values are `false`.

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

The OR (`||`) operator returns `false` only when both values are `false`.

### NOT (!)
The NOT (`!`) operator inverts the boolean value. It turns `true` into `false` and `false` into `true`.

# Using Logical Operators
Logical operators are often used to combine conditions. For example, to check if two values are greater than `4` or greater than `1`, you can use the AND (`&&`) operator.

let a = 5, b = 3;

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

# Priority
Logical operations have a lower priority than comparison operations, which, in turn, have a lower priority than mathematical operations.
