## Check if number is zero in JavaScript

In this tutorial, you are given a number. Write a JavaScript program to check if the number is zero `0`

.

## Solution

A number is zero if it is equal to `0`

. To check if given number is zero, we can use comparison equal-to operator to check if given number is equal to `0`

.

## Program

1. In the following program, we are given a number in `n`

. We shall check if `n`

is zero.

```
let n = 0;
if ( n == 0 ) {
console.log('zero');
} else {
console.log('not a zero');
}
```

We have used the condition as a boolean expression in if-else statement.

2. Now, we shall take a non-zero number in `n`

, and programmatically check if value in `n`

is zero or not.

```
let n = 7;
if ( n == 0 ) {
console.log('zero');
} else {
console.log('not a zero');
}
```
