Things to note when converting string to json

I have been working on a post for a day, sometimes it is normal and sometimes it is wrong!

let str = "{'name':'wanglei'}";
let obj = JSON.parse(str);

The above will report an error:

VM143:1 Uncaught SyntaxError: Unexpected token ' in JSON at position 1    
at JSON.parse (<anonymous>)    
at <anonymous>:1:6
str = &#39;{"name":"wanglei"}&#39;;

That’s it!

key and value must be in double quotes and comply with json specifications
