Note that in ES6, even in strict mode, the following will not cause an error:<br>

var books = {<br>

Might you know the ES6 specification paragraph?<br>

Wondering why they might deviate from prior strictness in JSON object model - duplicate keys can't be represented as an object.

This will be important for JSON linters to catch, unless we want to do streaming JSON (we don’t).<br>

I had trouble getting jsonlint or jshint to operate on your example, they balked mysteriously until replacing left-quote/right-quote characters. Also jslint failed silently under IE.<br>
<br>
This strict version of your example works:<br>
==============<br>
{ "books":{<div class="quoted-text"><br>
<br>
"title":"Understanding ECMAScript 6",<br>
<br></div>
"title2":"JavaScript: The Good, the Bad and the Ugly"<br>
}<br>
}<br>
==============<br>
<br>
jslint and jshint report "duplicate key" for:<br>
<br>
==============<br>
{ "books":{<div class="quoted-text"><br>
<br>
"title":"Understanding ECMAScript 6",<br>
<br>
"title":"JavaScript: The Good, the Bad and the Ugly"<br>
}<br>
}<br></div>
==============<br>
<br>
if ES6 checkbox is selected, jslint still reports: Duplicate 'title'.<br>
<br>
So maybe we are OK on this issue?<br></blockquote></div></div></div><div dir="auto"><br></div><div dir="auto">Probably. Thanks for checking. I don't know if we can test JSON schema because I think the validators require a JS object.</div><div dir="auto"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
