bigint

The bigint version of the {@link hrtime()} method returning the current high-resolution real time in nanoseconds as a bigint.

Unlike {@link hrtime()}, it does not support an additional time argument since the difference can just be computed directly by subtraction of the two bigints.

import { hrtime } from 'node:process';

const start = hrtime.bigint();
// 191051479007711n

setTimeout(() => {
  const end = hrtime.bigint();
  // 191052633396993n

  console.log(`Benchmark took ${end - start} nanoseconds`);
  // Benchmark took 1154389282 nanoseconds
}, 1000);
