## Problem Statement

given a number, write a JavaScript program to check if the number is negative

## Solution

a number is negative if it is less than `0`

. to check if given number is negative, we have to check if it is less than `0`

. we can use comparison less than operator to check if given number is less than `0`

## Program

1. given number is `n`

. check if `n`

is negative

```
let n = -4;
if ( n < 0 ) {
console.log('negative number');
} else {
console.log('not a negative number');
}
```

we have used the condition in if-else statement

2. positive number in `n`

```
let n = 6;
if ( n < 0 ) {
console.log('negative number');
} else {
console.log('not a negative number');
}
```
