4. Step-by-Step Guides, Tutorials, and Examples

4.1 Python Implementation

for i in range(1, 101):
    if i % 3 == 0 and i % 5 == 0:
        print("FizzBuzz")
    elif i % 3 == 0:
        print("Fizz")
    elif i % 5 == 0:
        print("Buzz")
    else:
        print(i)

Explanation:

The for loop iterates through numbers from 1 to 100.
The if and elif statements check for divisibility by 3 and 5 using the modulo operator (%).
If a number is divisible by both 3 and 5, "FizzBuzz" is printed.
If a number is divisible by only 3, "Fizz" is printed.
If a number is divisible by only 5, "Buzz" is printed.
Otherwise, the number itself is printed.

4.2 JavaScript Implementation

for (let i = 1; i &lt;= 100; i++) {
  if (i % 3 === 0 &amp;&amp; i % 5 === 0) {
    console.log("FizzBuzz");
  } else if (i % 3 === 0) {
    console.log("Fizz");
  } else if (i % 5 === 0) {
    console.log("Buzz");
  } else {
    console.log(i);
  }
}

Explanation:

The for loop iterates through numbers from 1 to 100.
The if and else if statements check for divisibility by 3 and 5 using the modulo operator (%).
The console.log() function prints the output to the console.

Tips and Best Practices:

Code Readability: Use meaningful variable names and comments to explain the logic.
Modularity: Break down the code into smaller, reusable functions (e.g., a checkFizzBuzz function that takes a number as input and returns the appropriate output).
Error Handling: Consider handling potential exceptions (e.g., if the input is not a number).

5. Challenges and Limitations

While FizzBuzz is a basic task, it can pose challenges for candidates who lack the fundamental programming knowledge or struggle with logical thinking.

5.1 Common Pitfalls:

Incorrectly Handling Conditional Logic: Mixing up the order of if and else if statements.
Off-by-One Errors: Incorrectly defining the loop range (e.g., starting from 0 instead of 1).
Ignoring Edge Cases: Not considering potential edge cases like 0 or negative numbers.

5.2 Limitations:

Limited Scope: FizzBuzz only tests a narrow range of programming concepts.
Lack of Real-World Context: It doesn't provide a real-world problem-solving context.
Over-Emphasis on Syntax: It can focus too much on specific language syntax rather than problem-solving.

5.3 Overcoming Challenges:
