Prime Numbers

There are different classes on primeString.js which can deal with primes. First thing to mention is if you want to work with numbers smaller than 9007199254740991, use prime-js.

`mathOperation.js`

Some different methods on a class to do all the necessary math operation for big numbers in js.

`primeString.js`

Prime class:
- How to run?
  
  let pr = new Prime(number, 1); // number should be string. eg: "123"
  
  console.log(pr.isPrime()); // isPrime : check if number is prime or not
  
  console.log(pr.numberDivisions()); // numberDivision: show all the divisions of a number

PrimeType class:
- How to run?
  
  let prr = new PrimeType(number, 1); // number: should be string
  
  console.log(prr.isTwinPrime()); // if the number is a Twin Prime
  
  console.log(prr.isPrimeChecking()); // if the number is a prime or not
  
  console.log(prr.isIsolatedPrime()); // if the number is an Isolated Prime
  
  console.log(prr.isSophiePrime()); // if the number is a Sophie Prime

PrimeInRange class:
- How to run?
  
  let pr = new PrimeInRange(number, "1"); // number should be string
  
  console.log(pr.primeToANumber()); // Will find all the primes till number, and will save it on prime-output-big folder.
  
  console.log(pr.primeRange()); // Will find all the primes between two numbers and will save it into primeInARange of a class. Then you need to run console.log(pr.primeInARange) to check all of them.

SearchForPrime class:
- How to run?
  
  let pr = new SearchForPrime(number); // number should be string
  
  console.log(pr.findTheProperFolder()); // If there are some files on prime-output-big, then this will find the proper folder to check if the number is prime or no. But what is proper folder? every folder inside the prime-output-big has a number ( eg: output-10000 ). This means that folder contains all the primes from 1 till the number. Then the proper folder to check if a number is prime or no is to check if that file inside a folder contains that number or no. If the number is bigger than what we have on prime-output-big, this is not helpful.
  
  console.log(pr.isPrime()) // if the number is prime or no.

PrimeFromText class:
- How to run?
  
  let pr = new PrimeFromText();
  
  console.log(pr.isPrime(number)); // check if a number is prime or not. The difference with SearchForPrime is that if it could not find the number on files, then it will use other classes to check if a number is prime or not.

PrimeWriter class: this class will deal with files and how to copy from them and how to write new files.
