Converting a JavaScript array to JSON [duplicate]

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

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.

He requested to start with {}.

Indeed. The question doesn't make sense. I don't think it is answerable in its current state.

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.

After editing, it converts one of the objects in the array to a JSON object instead of converting the array to one.

That now does what the question is asking. The requirement is still bizarre though.

True that... Really dunno why the OP needs this kind of black magic.

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);
