Is It Negative Zero (-0)? js

// 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).
