JavaScript: Check two given integers, whether one is positive and another one is negative

JavaScript Basic: Exercise-20 with Solution

Write a JavaScript program to check two given integers whether one is positive and another one is negative.

This JavaScript program checks two given integers to determine if one is positive and the other is negative. It utilizes conditional statements and logical operators to evaluate whether one integer is greater than zero (positive) and the other is less than zero (negative), returning true if both conditions are met and false otherwise.

Sample Solution:

JavaScript Code:

// Define a function named positive_negative that takes two parameters, x and y
function positive_negative(x, y) {
  // Check if either x is negative and y is positive, or x is positive and y is negative
  if ((x < 0 && y > 0) || (x > 0 && y < 0)) {
    // If true, return true
    return true;
  } else {
    // If false, return false
    return false;
  }
}

// Log the result of calling the positive_negative function with the arguments 2 and 2 to the console
console.log(positive_negative(2, 2));

// Log the result of calling the positive_negative function with the arguments -2 and 2 to the console
console.log(positive_negative(-2, 2));

// Log the result of calling the positive_negative function with the arguments 2 and -2 to the console
console.log(positive_negative(2, -2));

// Log the result of calling the positive_negative function with the arguments -2 and -2 to the console
console.log(positive_negative(-2, -2)); 

Output:

false
true
true
false

Flowchart:

ES6 Version:

// Using ES6 arrow function syntax to define the positive_negative function
const positive_negative = (x, y) => ((x < 0 && y > 0) || (x > 0 && y < 0));

// Log the result of calling the positive_negative function with the arguments 2 and 2 to the console
console.log(positive_negative(2, 2));

// Log the result of calling the positive_negative function with the arguments -2 and 2 to the console
console.log(positive_negative(-2, 2));

// Log the result of calling the positive_negative function with the arguments 2 and -2 to the console
console.log(positive_negative(2, -2));

// Log the result of calling the positive_negative function with the arguments -2 and -2 to the console
console.log(positive_negative(-2, -2));
