Language Speed Comparison - Primes

This test compares the speed of Python, Java, Node.js, C♯, C++, PHP, C, Go, Kotlin, Rust, Ruby, Dart, Swift, R and Visual Basic (the 15 most common languages that can output primes to a console) by comparing the speed of implementations of an algorithm similar to
rwh_primes. The output of the programs is not shown; you only see the time taken by each program.
