引用中的报错信息 "TypeError: Cannot read properties of undefined (reading 'forEach')" 表明在程序的第6行的代码中,尝试对一个未定义的属性进行forEach操作。这个错误的原因是在编写代码时没有使用分号来分隔不同的语句,导致编译器无法正确解读程序。所以报错了。中提到了对象的getter和setter的特例,在这个特例中,对于没有getter或setter的属性,尝试访问其name属性时会报错。所以在你的报错信息中,当尝试访问'foo'属性的name属性时,会出现"TypeError: Cannot read property 'name' of undefined"的错误信息。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
