In JavaScript, the NEGATIVE_INFINITY property symbolizes negative infinity and is a numerical value obtained by dividing a negative number by zero. Essentially, it represents a number that is smaller than any other number. Key properties include:

• It's a static property, accessible without object instantiation.
• The value mirrors the negative of the infinity property of the global object.

The values behave differently than the mathematical infinity:

1. Any positive value, including POSITIVE_INFINITY, multiplied by NEGATIVE_INFINITY is NEGATIVE_INFINITY.
2. Any negative value, including NEGATIVE_INFINITY, multiplied by NEGATIVE_INFINITY is POSITIVE_INFINITY.
3. Zero multiplied by NEGATIVE_INFINITY is NaN.
4. NaN multiplied by NEGATIVE_INFINITY is NaN.
5. NEGATIVE_INFINITY, divided by any negative value except NEGATIVE_INFINITY, is POSITIVE_INFINITY.
6. NEGATIVE_INFINITY, divided by any positive value except POSITIVE_INFINITY, is NEGATIVE_INFINITY.
7. NEGATIVE_INFINITY, divided by either NEGATIVE_INFINITY or POSITIVE_INFINITY, is NaN.
8. Any number divided by NEGATIVE_INFINITY is zero.
