JS内存管理生命周期和垃圾回收机制

JS内存管理生命周期和垃圾回收机制最近在看大神写的专栏，很精辟，笔者想通过总结的方式加深理解，不一定准确，只是笔者自己的想法，欢迎指正。TL;DRJS 的内存管理生命周期：分配、读写、释放垃圾回收机制的算法：引用计数法、标记清除法内存泄漏成因：闭包引起的共享父作用域、变量没声明、未清除...

js内存管理系列篇三：垃圾回收机制

js作为一门高级程序语言，具有自动的垃圾回收机制，那我们来探究一下它的原理及机制。引用计数垃圾收集这是最初级的垃圾收集算法。此算法把“对象是否不再需要”简化定义为“对象有没有其他对象引用到它”。如果没有引用指向该对象（零引用），对象将被垃圾回收机制回收。举个例子:let o = { a:{ b...
