Write a Javascript Program to Check if a number is Positive, Negative, or Zero

In JavaScript, we can easily determine whether a number is positive, negative, or zero by using an if statement.

Here’s an example program that demonstrates this:

// Define a variable to hold the number
let num = 5;

// Check if the number is positive
if (num > 0) {
  console.log("The number is positive.");
}

// Check if the number is negative
if (num < 0) {
  console.log("The number is negative.");
}

// Check if the number is zero
if (num === 0) {
  console.log("The number is zero.");
}

In this program, we first define a variable num and assign it the value of 5. We then use three separate if statements to check if num is positive, negative, or zero.

The first if statement checks if num is greater than 0. If it is, then we log the message “The number is positive.” to the console.

The second if statement checks if num is less than 0. If it is, then we log the message “The number is negative.” to the console.

The third if statement checks if num is equal to 0. If it is, then we log the message “The number is zero.” to the console.

By using these three if statements, we can easily determine whether a given number is positive, negative, or zero in JavaScript.
