How to use ternary operator In Javascript
In this approach we are using ternary operator. Ternary operator is shorthand of “if-else” statement. If “n<0” is true then it will print “Negative” else it will check for another condition and it will print result accordingly.
Example: It describes how we can find the given number is Positive, Negative, or Zero using ternary operator
let n = 0;
// Using ternary operator
// for solving the
// problem
let ans = n < 0 ? "Negative" : n > 0 ? "Positive" : "Zero";
// Printing result in
// console
console.log(ans);
Output
Zero
Time complexity: O(1) as it is doing constant operations
Space complexity: O(1) as it is using constant space for variables
JavaScript Program to Check if a Given Integer is Positive, Negative, or Zero
In this article, we will discuss how we can determine whether the given number is Positive, Negative, or Zero. As we know if the number is less than 0 then it will be called a “Negative” number if it is greater than 0 then it will be called a “Positive” number. And if it doesn’t lie between them, then it will be 0.
Example:
Input: 10
Output: Positive number
Input: -12
Output: Negative number
Input: 0
Output: Zero
These are the following ways by which we can find out whether the number is Positive, Negative, or Zero:
