@u4/prime v1.0.1
@u4/prime
This small package contains simple prime number utilities with no extra stuff.
why an other simple prime number tester / generator
I'm publishing this package because no available prime's number package have the required quality or features to be used. I only need to find some random prime numbers to loop over ℤ/nℤ ring.
I tryed a lot's of implementations
| Name | Size in node_modules | Observation |
|---|---|---|
| prime-number | 28kB | store all vistited values in memory, contains only isPrime function |
| nprime | 776kB | too large + recursive implenetation |
| prime-nummers | 4840kB | 4840 KB WTF !! |
| prime-q | 54280kB | 54MB !! |
| prime-number-boolean | 24kB | using +1 loop + dirty code |
| is-prime-number | 24kB | using +1 in test loop + have typing |
| prime-number-search | 48kB | works with string but do not support big numbers so, useless |
| prime_numbers | 16kB | console.log results +1 loop, do not return result ! |
How it works
Using default import
import isPrime from '@u4/prime';
console.log(isPrime(7))Using named import
import {isPrime, nextPrime, prevPrime} from '@u4/prime';
console.log(isPrime(7))Using * as import
import * as Prime from '@u4/prime';
console.log(Prime.isPrime(7))
