22. JavaScript Program to find Positive numbers, Negative numbers and Zeros of given numbers.
How does this program work?
- In this program we are going to learn about how to find the Positve numbers, Negative numbers and Zeros of given real numbers using JavaScript.
- Declare n variable, array elements stored in this variable.
- Each element is compared with 0, If the element is greater than 0 then the element is postive and the element is less than 0 then the element is negative otherwise the element is zero.
- After doing this for each element of the given array, then we get the postive, negative and zeros numbers of given numbers.
Here is the code

}
document.write("Given numbers : "+ array+ "</br>");
document.write("Number of +ve numbers are: "+ positive+"</br>");
document.write("Number of -ve numbers are: "+ negative+"</br>");
document.write("Number of zeros numbers are: "+ zero);
