title: How to read/write a bigint from buffer in node.js 10?
body: <p>I see that BigInt is supported in node 10. However, there's no ReadBigInt() functionality in the Buffer class.</p>
  
  <p>Is it possible to somehow go around it? Perhaps read 2 ints, cast them to BigInt, shift the upper one and add them to reconstruct the bigint? </p>
