JavaScript Code

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');
}
