等到函数在递归函数中完成

Given I have a recursive method:

鉴于我有一个递归方法:

tests = {
  add: function (data, option, dataSet) {
    if(option) {
      dataSet.forEach(function (values) {
        this.add(values.data, false);
      }, this);
    }
    console.log(data.name)
  }
}

And I would call this by using

我会用这个来称呼它

tests.add({name: 'test1'}, true, [{data: {name: 'test2'}}]);

I assume this would log 'test2' before 'test1' in all cases, but in a lot of cases this does not happen. As far I know the forEach function should be blocking the execution of other lines, but this simply does not happen.

我认为在所有情况下都会在'test1'之前记录'test2',但在很多情况下这不会发生。到目前为止,我知道forEach函数应该阻止其他行的执行,但这根本不会发生。

Bit of context: The code should add certain components on a webpage. Those components can depend on other components (which are in dataSet). These dependencies should always be recursively added first.

上下文:代码应该在网页上添加某些组件。这些组件可以依赖于其他组件(在dataSet中)。应始终首先递归地添加这些依赖项。

Any ideas?

The reason for this inconsistency is that console.log is not a synchronous function. Read more here

这种不一致的原因是console.log不是同步函数。在这里阅读更多
