Node.js process.hrtime.bigint()用法及代碼示例

process.hrtime.bigint()

• 返回： <bigint>

process.hrtime() 方法的 bigint 版本以 bigint 的形式返回當前的 high-resolution 實時(以納秒為單位)。

與 process.hrtime() 不同，它不支持額外的 time 參數，因為可以直接通過減去兩個 bigint 來計算差異。

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);
