v8 中的垃圾回收机制分为三种
v8
Scavenge
from space
to space
Mark-Sweep
Mark-Compact
Sorry, something went wrong.
当一个函数执行结束之后,JavaScript 引擎会通过向下移动 ESP 来销毁该函数保存在栈中的执行上下文。 要回收堆中的垃圾数据,就需要用到 JavaScript 中的垃圾回收器了。 代际假说(The Generational Hypothesis),是垃圾回收领域中一个重要的术语,后续垃圾回收的策略都是建立在该假说的基础之上的,所以很是重要。 代际假说有以下两个特点:
全停顿
增量标记
使用增量标记算法,可以把一个完整的垃圾回收任务拆分为很多小的任务,这些小的任务执行时间比较短,可以穿插在其他的 JavaScript 任务中间执行,增强用户体验。
