# Day 2: Conditional Statements: If-Else | 10 Days of JavaScript | HackerRank Solution

Hello coders, today we are going to solve Day 2: Conditional Statements: If-Else HackerRank Solution which is a part of 10 Days of JavaScript Series.

Contents

## Objective

In this challenge, we learn about if-else statements. Check out the attached tutorial for more details.

Complete the `getGrade(score)` function in the editor. It has one parameter: an integer, score, denoting the number of points Julia earned on an exam. It must return the letter corresponding to her grade according to the following rules:

• If 25 < score <= 30, then grade = A.
• If 20 < score <= 25, then grade = B.
• If 15 < score <= 20, then grade = C.
• If 10 < score <= 15, then grade = D.
• If 5 < score <= 10, then grade = E.
• If 0 < score <= 5, then grade = F.

## Input Format

Stub code in the editor reads a single integer denoting score from stdin and passes it to the function.

## Constraints

• 0 <= score <= 30

## Output Format

The function must return the value of grade (i.e., the letter grade) that Julia earned on the exam.

Sample Input 0

``11``

Sample Output 0

``D``

Explanation 0

Because score = 11, it satisfies the condition 10 < score <= 15 (which corresponds to `D`). Thus, we return `D` as our answer.

## Solution – Day 2: Conditional Statements: If-Else

```'use strict';

process.stdin.resume();
process.stdin.setEncoding('utf-8');

let inputString = '';
let currentLine = 0;

process.stdin.on('data', inputStdin => {
inputString += inputStdin;
});

process.stdin.on('end', _ => {
inputString = inputString.trim().split('\n').map(string => {
return string.trim();
});

main();
});

return inputString[currentLine++];
}

if(score > 25 && score <= 30){
return("A");
}else if(score > 20 && score <= 25){
return("B");
}else if(score > 15 && score <= 20){
return("C");
}else if(score > 10 && score <= 15){
return("D");
}else if(score > 5 && score <= 10){
return("E");
}else if(score > 0 && score <= 5){
return("F");
}
