// Is It Negative Zero (-0)?
// In JavaScript, negative zero (-0) is a valid number. It is different from positive zero (+0), which is also a valid number.
// The difference between negative and positive zero is that negative zero has the same sign as the number it is associated with. So when negative zero is added to a number, the result will be negative. Similarly, when positive zero is added to a number, the result will be positive.
// Examples of negative zero:
// Adding a negative number to negative zero
let result1 = -2 + (-0); // result1 = -2
// Adding a positive number to negative zero
let result2 = 2 + (-0); // result2 = 2
// Examples of positive zero:
// Adding a negative number to positive zero
let result3 = -2 + (+0); // result3 = -2
// Adding a positive number to positive zero
let result4 = 2 + (+0); // result4 = 2
// When compared to each other, negative and positive zero are considered equal
let result5 = (-0) === (+0); // result5 = true
// However, when compared to any other number, negative and positive zero are considered different
let result6 = (-0) === 1; // result6 = false
```

Negative zero (-0) is a valid number in JavaScript, which is different from positive zero (+0). The difference between the two is that negative zero has the same sign as the number it is associated with. So when negative zero is added to a number, the result will be negative. Similarly, when positive zero is added to a number, the result will be positive. For example, when adding a negative number to negative zero, the result will be negative (e.g. -2 + (-0) = -2). When adding a positive number to negative zero, the result will be positive (e.g. 2 + (-0) = 2). The same applies for positive zero. When compared to each other, negative and positive zero are considered equal (e.g. (-0) === (+0) = true). However, when compared to any other number, negative and positive zero are considered different (e.g. (-0) === 1 = false).
