process.hrtime.bigint()

• 返回：<bigint>

process.hrtime() 方法的 bigint 版本，以 bigint 形式返回当前高精度实时时间（纳秒）。

【The bigint version of the process.hrtime() method returning the current high-resolution real time in nanoseconds as a bigint.】

与 process.hrtime() 不同，它不支持额外的 time 参数，因为差值可以直接通过两个 bigint 相减来计算。

【Unlike process.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);const { hrtime } = require('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);拷贝
