Check if number is positive in JavaScript

In this tutorial, you are given a number. Write a JavaScript program to check if the number is positive.

Solution

A number is positive if it is greater than 0. To check if given number is positive, we have to check if it is greater than 0. We can use comparison greater than operator to check if given number is greater than 0.

Program

1. In the following program, you are given a number in n. We shall check if n is a positive number.

let n = 4;
if ( n > 0 ) {
    console.log('positive number');
} else {
    console.log('not a positive number');
}

we have used the condition in if-else statement

2. Now, we shall take a negative number in n, and programmatically check if n is positive or not.

let n = -3;
if ( n > 0 ) {
    console.log('positive number');
} else {
    console.log('not a positive number');
}
