process.hrtime.bigint()

• 返回: <bigint>

process.hrtime() 方法的 bigint 版本以纳秒为单位返回当前高解析度实时作为 bigint。

与 process.hrtime() 不同，它不支持额外的 time 参数，因为可以直接通过减去两个 bigint 来计算差异。

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

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

  console.log(`Benchmark took ${end - start} nanoseconds`);
  // 基准测试耗时 1154389282 纳秒
}, 1000);

• Returns: <bigint>

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

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.

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

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

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