Example: In this example, we are using the if..else statement to verify whether the given number is positive or
negative.
• Javascript
let num = -10;

if (num > 0)
console.log(“The number is positive.”);
else
console.log(“The number is negative”);
Output

The number is negative
Approach 3: Using Switch Statement
The switch case statement in JavaScript is also used for decision-making purposes. In some cases, using the
switch case statement is seen to be more convenient than if-else statements.

Syntax:
switch (expression) {
case value1:
statement1;

break;
case value2:
statement2;
break;
.

.
case valueN:
statementN;
break;
default:

statementDefault;
}
Example: In this example, we are using the above-explained approach.
• Javascript
let num = 5;

switch (num) {
case 0:
console.log(“Number is zero.”);
break;

case 1:
console.log(“Nuber is one.”);
break;
