I’m pretty proud of this one as well.

```
package sieve
//Sieve Uses the Sieve of Eratosthenes to calculate primes to a certain limit
func Sieve(limit int) []int {
var listOfPrimes []int
markers := make([]bool, limit)
for i := 2; i < limit; i++ {
if !markers[i] {
for j := i + i; j < limit; j += i {
markers[j] = true
}
listOfPrimes = append(listOfPrimes, i)
}
}
return listOfPrimes
}
```
