The Sieve of Eratosthenes is a highly efficient algorithm for finding all prime numbers up to a specified limit. It works by iteratively marking the multiples of each prime number starting from 2. This method quickly eliminates composite numbers and retains prime numbers. The algorithm can be easily implemented in various programming languages, such as JavaScript, and is crucial for tasks in modern cryptography and large number testing.
