process.hrtime.bigint()

• 返回:<bigint>

  \Returns: <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。

\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,因为差异可以直接通过减去两个 bigint 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
