Browserling itself is an online cross-browser testing service powered by alien technology. Behind the scenes, it's actually powered by our web developer tools that are used by millions of people every month. A prime number (or a prime) is a natural number that has exactly two distinct natural number divisors: 1 and itself.
This prime number sequence generator was created by me and my team at Browserling. This prime numbers generator is used to generate the list of prime numbers from 1 to a number you specify. Finally, it calls the join(separator) function on the array that holds the primes and this separates them with the separator character (specified in options). As there are infinitely many primes, this loop runs until it finds as many sequential primes as specified in the count options. To do this, it uses the isPrime(n) function, which implements the Sieve of Eratosthenes algorithm to check if the given number n has any divisors except for 1 and itself. Then, it starts a loop from start with a step of 2 and in this loop, it tests whether the current number is prime. First, it checks if the start value (specified in options) is odd if it's not, it adds 1 to it (prime numbers can't be even). This prime number list generator works entirely in your browser and is written in JavaScript. How Does This Prime Number Sequence Generator Work?
