What does “yield break;” do in C#?

IEnumerable<uint> FindPrimes(uint startAt, uint maxCount)
{
for (var i = 0UL; i < maxCount; i++)
{
startAt = NextPrime(startAt);
yield return startAt;
}
Debug.WriteLine("All the primes were found.")...
Convert a binary NodeJS Buffer to JavaScript ArrayBuffer
...
Instances of Buffer are also instances of Uint8Array in node.js 4.x and higher. Thus, the most efficient solution is to access the buf.buffer property directly, as per https://stackoverflow.com/a/31394257/1375574. The Buffer constructor also takes an ArrayBufferVie...

Get Base64 encode file-data from Input Form
...ay (or it doesn't work), look at readAsArrayBuffer(). This will give you a Uint8Array and you can use the method specified. This is probably only useful if you want to mess with the data itself, such as manipulating image data or doing other voodoo magic before you upload.
There are two methods:

C++ performance challenge: integer to std::string conversion
