javascript - 如何使用变量从 json 中取出对象？

Question

我有一个小问题，我无法理解。

let content = getData() //This will return a json in the variable content
content[0] //This is the output that i want but instead of [0], I want to store this into a variable

let path = "[0]"
content.path //something like that but the good way, can't figure it out how i could do this

谢谢！

尝试使用括号表示法，因为这允许动态值作为键名：

let path = "0";
content[path]
