Lets assume you receive the following JSON from a web server via an API call or some form of Scraping method 假设您通过API调用或某种形式的Scraping方法从Web服务器接收以下JSON
'{ "firstName":"Foo", "lastName":"Bar" }'
To access this data you first need to parse the raw JSON and form a Javascript object 要访问此数据，您首先需要解析原始JSON并形成一个Javascript对象
let response = JSON.parse('{ "firstName":"Foo", "lastName":"Bar" }');
This forms an object which we can access relativly simply 这形成了一个我们可以相对简单地访问的对象
let firstName = response["firstName"];
let lastName = response["lastName"];
