Primitive是值传递(passed by value),Object是引用传递(passed by reference)。 上面说到,Javascript变量在stack保存的是地址引用,为什么又说Primitive是值传递呢?Javascript中所有Primitive都是immutable的。在传递Primitive时,JS engine在heap上复制一个值相同的Primitive,然后把新变量的引用传递出去,这就是所谓JS中的值传...
一、概念 我们需了解什么是按值传递(call by value),什么是按引用传递(call by reference)。在计算机科学里,这个部分叫求值策略(Evaluation Strategy)。它决定变量之间、函数调用时实参和形参之间值是如何传递的。 按值传递 VS. 按引用传递 按值传递(call by value)是最常用的求值策略:函数的形参是被调用时所传...
