console.timeEnd([label])

• label <string> 默认值: 'default'

停止之前通过调用 console.time() 启动的计时器并将结果打印到 stdout：

console.time('100-elements');
for (let i = 0; i < 100; i++) {}
console.timeEnd('100-elements');
// 打印 100-elements: 225.438ms

• label <string> Default: 'default'

Stops a timer that was previously started by calling console.time() and prints the result to stdout:

console.time('100-elements');
for (let i = 0; i < 100; i++) {}
console.timeEnd('100-elements');
// prints 100-elements: 225.438ms
