Converting a JavaScript array to JSON

Question

So I have an array that looks like this:

var me = [
    {'we':'me','see':'tree','lee':'bee'},
    {'we':'me','see':'tree','lee':'bee'},
    {'we':'me','see':'tree','lee':'bee'},
    {'we':'me','see':'tree','lee':'bee'}
];

How do I convert this to a JSON object starting with '{' and ending with '}'

What property names would you want? It doesn't make sense to try to convert a JavaScript array into a JSON object. — Quentin, Apr 25 '14 at 11:46

With JSON.stringify?

var me =[
    {'we':'me','see':'tree','lee':'bee'},
    {'we':'me','see':'tree','lee':'bee'},
    {'we':'me','see':'tree','lee':'bee'},
    {'we':'me','see':'tree','lee':'bee'}
];

console.log(JSON.stringify(me));    // returns whole JSON.
console.log(JSON.stringify(me[0])); // returns what you want, 'starting with {}'.

//    if you want to start with {} with all data:
console.log(JSON.stringify({me:me}));

The question is asking to convert the *array* to a JSON object, not one of the objects inside it. – Quentin Apr 25 '14 at 11:47
He requested to start with {}. – Kai Apr 25 '14 at 11:48
Indeed. The question doesn't make sense. I don't think it is answerable in its current state. – Quentin Apr 25 '14 at 11:48

Like this:

JSON.stringify(me.reduce(function(o, v, i) {
    o[i] = v;
    return o;
}, {}));

That won't work. That will give you a JSON array, not an object. – Quentin Apr 25 '14 at 11:46
After editing, it converts one of the objects in the array to a JSON object instead of converting the array to one. – Quentin Apr 25 '14 at 11:49
That now does what the question is asking. The requirement is still bizarre though. – Quentin Apr 25 '14 at 11:53

True that... Really dunno why the OP needs this kind of black magic. – Klemen Tusar Apr 25 '14 at 11:55

var myJsonString = JSON.stringify(me);

UPDATED

var me =[
{'we':'me','see':'tree','lee':'bee'},
{'we':'me','see':'tree','lee':'bee'},
{'we':'me','see':'tree','lee':'bee'},
{'we':'me','see':'tree','lee':'bee'}
];


var myjson={'list':""}
myjson.list=me;
var myJsonString = JSON.stringify(myjson);
console.log(myJsonString);
