JSON.parse fails on array with object

Question

In chrome, using this code

JSON.parse('[ "Rectangle", { width: 10 } ]')

throws me a

SyntaxError: Unexpected token w

Internet Explorer 11(.0.9600) has a similar behaviour: "Invalid character".

According to the definitions at http://json.org/, this syntax is clearly allowed and boils down to an array containing two elements: a string "Rectangle" and an object with one single property width and its value 10

What's wrong with it?

Asad is right. FYI, the exact same error occurs in Chrome (and should occur in other browsers). — pickypg

In JSON, object keys are strings, and therefore need to have quotes around them

JSON.parse('[ "Rectangle", { "width": 10 } ]')

Another option is to convert it to proper JSON first:

let obj = ["Rectangle",{ width: 10 }];
obj = JSON.parse(JSON.stringify(obj));
