case 2:

console.log(“Number is two.”);
break;
default:
console.log(“Number is greater than 2.”);
};
Output
Number is greater than 2.
Approach 4: Using the Ternary Operator (Conditional Operator)
The conditional operator, also referred to as the ternary operator (?:), is a shortcut for expressing conditional
statements in JavaScript.
Syntax:
condition ? value if true : value if false

Example: In this example, we are using the ternary operator to find whether the given number is positive or
negative.
• Javascript

let num = 10;
let result = num >= 0 ? “Positive” : “Negative”;
console.log(`The number is ${result}.`);
Output
The number is Positive.
Approach 5: Using For loop
In this approach, we are using for loop in which the execution of a set of instructions repeatedly until some
condition evaluates and becomes false
Syntax:
for (statement 1; statement 2; statement 3) {
// Code here . . .
}
Example: In this example, we are using Iterative Statement as a for loop, in which we find the even number
between 0 to 10.
• Javascript
for (let i = 0; i <= 10; i++) {
if (i % 2 === 0) {
console.log(i);
}
};
Output:
0
2
