当调用堆栈为空时,我知道消息从队列进入调用堆栈。但是,如果事件循环可以直接将消息从队列推送到调用堆栈而不需要等待,这不是更好吗?这种行为背后的原因是什么?如果事件循环会在确切的时间推送消息,那么我们总是可以依赖于函数,如setTimeout等。

// some blocking operations
for(let i = 0; i < 500000000; i++){

if (context) {
if (predicate.call(context, collection[i], i, collection)) {
result = true;
break;
我正在运行一个three.js示例代码,它的three.js版本是0.124。 createObj() {
const geometry = new THREE.InstancedBufferGeometry();
const baseGeometry = new THREE.BoxGeometry(2, 2, 20, 2, 2, 6);
// Copy attributes of the base Geometry to the instancing Geometry
geometry.copy(baseGeometry);
} 当代码在'
