generateNthPrimeNumber()

Step 1: Understand The Problem

The problem is asking us to generate the nth prime number. So, if the input is 3, the output should be 5, because 5 is the 3rd prime number (after 2 and 3).

Step 2: Initialize Variables

First, let's initialize our function generateNthPrime() with one parameter n. After that, we'll need some variables: • primeCount to keep track of how many prime numbers we've found (initialize to 0) • num to hold the current number we're checking (initialize to 2, the first prime number)

Here's how that looks in code:

function generateNthPrime(n) {
  let primeCount = 0;
  let num = 2;
}

Step 3: Create a Helper Function

Next, we need to build a helper function isPrime() to check if num is a prime number or not, which we'll use in the following step.

Here is the code for isPrime() function:

function isPrime(num) {
  for(let i = 2; i < num; i++)
    if(num % i === 0) return false;
  return num !== 1;
}

Step 4: Find the nth Prime Number

Now, let's build the loop that finds the nth prime number by using our isPrime() function. As long as primeCount is less than n, we'll continue to increment num and check if it's a prime number. If it is, we'll increment primeCount.

while(primeCount < n) {
  if(isPrime(num)) {
    primeCount++;
  }
  num++;
}

Step 5: Return the nth Prime Number

Finally, since num has been incremented one extra time after finding the nth prime, we'll need to subtract 1 before returning it.

Here is the final function:

function generateNthPrime(n) {
  let primeCount = 0;
  let num = 2;

  function isPrime(num) {
    for(let i = 2; i < num; i++)
      if(num % i === 0) return false;
    return num !== 1;
  }

  while(primeCount < n) {
    if(isPrime(num)) {
      primeCount++;
    }
    num++;
  }

  return num - 1;
}

This code works, but note that it can be optimized further, especially the isPrime() function. For larger inputs, this code might run slowly.
