A common use of JSON is to exchange data to/from a web server.
When receiving data from a web server, the data is always a string.
Parse the data with JSON.parse(), and the data becomes a JavaScript object.
JSON.parse()
Imagine we received this text from a web server:
'{"name":"John", "age":30, "city":"New York"}'
Use the JavaScript function JSON.parse() to convert text into a JavaScript object:
const obj = JSON.parse('{"name":"John", "age":30, "city":"New York"}');
Make sure the text is in JSON format, or else you will get a syntax error.
