PrimeChecker_Core

A library for generating a list of primes until (and including) a certain number.

Installation

npm install primechecker_core --save

Usage

Some Usage Examples here will be in TypeScript. In JavaScript, these will be similar, but not identical

Loading

const primechecker = require("primechecker_core")

Getting prime numbers until and including a number

If said number is 100, you would use...

const result = primechecker.calculatePrimes(100)

Which returns a table:

{
    primes: [
        2,   3,  5,  7, 11, 13, 17, 19,
        23,  29, 31, 37, 41, 43, 47, 53,
        59,  61, 67, 71, 73, 79, 83, 89,
        97
    ]
    lastPrime: 97
}

NOTICE: Numbers previously generated will be listed here, regardless of the number you input. As an example, if you ran calculatePrimes(100) then calculatePrimes(10), the primes table would include the numbers 11-97 aswell.

Clearing the current data

Lets say for some reason, you didnt want the table anymore, and wanted to freshly generate it. You could use:

primechecker.resetPrimes()

Which returns nothing.

Questions which might be on your mind

Why does this have _core in the name?

Because I'm making an electron app based upon this.

Why did you make this?

Someone made a scratch project and sent me it related to this topic, but it wasn't that complete, so i made this instead.
