JavaScript Code

Problem Statement

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. given number is n. 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 in if-else statement

2. non-zero number in n

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