@ohos.util.PlainArray.get

官方API文档

测试用例 1: 测试PlainArray容器get方法

function test_get(loopCount: number) {
  const plainArray = new PlainArray<string>();
  for (let i = 0; i < loopCount; i++) {
    plainArray.add(i, `Value${i}`);
  }
  const startTime = new Date();
  for (let i = 0; i < loopCount; i++) {
    plainArray.get(i);
  }
  const endTime = new Date();
  const executionTime = endTime.getTime() - startTime.getTime();
  const averageTime = executionTime / loopCount;
  console.log(`!${test_id}: ${averageTime} ms`);
}
