In this tutorial, we will see a JavaScript program to check if the given input number is positive or negative.
JavaScript has a single data type that represents a Number, the number can be Integer or Float.
To determine if the given number is positive or negative, we can use the following function.
const checkPositivity = (num) => {
if(num === 0){
console.log("It is a zero");
}else if (num < 0){
console.log("It is a negative number");
}else{
console.log("It is a positive number");
}
}
checkPositivity(0); // It is a zero
checkPositivity(1); // It is a positive number
checkPositivity(-1); // It is a negative number
