setInterval和setTimeout是两个常用的实现动画的接口,用以间隔更新元素的风格与布局。 动画效果的帧率最优化的情况是使用一个timer完成多个对象的动画效果,其原因在于多个timer的调用本身就会损耗一定 性能。 1 2 3 4 5 6 setInterval(function() { animateFirst(''); }, 10); setInterval(function() { animat...

vara =function() {varsmallStr = 'x';varlargeStr =newArray(1000000).join('x');returnfunction(n) {returnsmallStr; }; }(); 我们不能再访问largeStr了,它已经是垃圾回收候选人了。【译者注:因为largeStr已不存在外部引用了】 定时器 最糟的内存泄漏地方之一是在循环中,或者在setTimeout()/ setInter...

This is turned off by default for performance reasons, but is safe to enable. Note that in the default configuration, without setting runScripts, the values of window.Array, window.eval, etc. will be the same as those provided by the outer Node.js environment. That is, window.eval ===...
New ES2015 APIs such as Map, Set, Weakmap, Weakset, Promises, and a variety of otherAPI changes This allows you to now write code such as the following: Using new language features in ES2015 Notice the class keyword used for theLayoutManagerclass, a template string for the message variabl...
