Problem 1
    Given a variable score, use a ternary operator to determine the
    performance level:
    • "Excellent" if score is 90 or above,
    • "Good" if score is between 60 and 89,
    • "Needs Improvement" if score is below 60.
    Test Cases:
    1. Input: score = 95
    Expected Output: "Excellent"
    2. Input: score = 75
    Expected Output: "Good"
    3. Input: score = 50
    Expected Output: "Needs Improvement"
    var score = 50; //Needs Improvement
    // var score = 75; //Good
    // var score = 95; //Excellent
    score >= 90
    ? console.log("Excellent")
    : score >= 60 && score < 89
    ? console.log("Good")
    : console.log ("Needs Improvement");

A:Output:
Needs Improvement

Problem 2
Given a variable day, use a ternary operator to check if it's a weekend:
• "Weekend" if day is "Saturday" or "Sunday",
• "Weekday" for any other day.
Test Cases:
1. Input: day = "Saturday"
Expected Output: "Weekend"
2. Input: day = "Monday"
Expected Output: "Weekday"
3. Input: day = "Sunday"
Expected Output: "Weekend"
A)var day = "Monday"; //Weekday
day == "Saturday" || day == "Sunday"
? console.log("Weekend")
: console.log("Weekday");

A:Output:
Weekday

Problem 3
    Given a string inputString, use the ternary operator to check if it is a
    palindrome. A string is considered a palindrome if it reads the same
    forwards and backwards.
    • Output: "Palindrome" if the string is a palindrome,
    • "Not a Palindrome" otherwise.
    
    Test Cases:
    1. Input: inputString = "madam"
    Expected Output: "Palindrome"
    2. Input: inputString = "hello"
    Expected Output: "Not a Palindrome"
    3. Input: inputString = "racecar"
    Expected Output: "Palindrome"
    4. Input: inputString = "world"
    Expected Output: "Not a Palindrome"
    var str = "madam"; //Palindrome
    var isPalindrome =
    str === str.split("").reverse().join("") ? "Palindrome": "Not a
    palindrome";
    console.log(isPalindrome);

A:Output:
Palindrome

Problem 4
    Input: HELLO
    Output:
    H
    HE
    HEL
    HELL
    HELLO
    var str = "HELLO";
    var output = "";
    for (i = 0; i <= str.length - 1; i++) {
    output += str[i];
    console.log(output);
    }

A:Output:
H
HE
HEL
HELL
HELLO
