I think this is a duplicate of http://stackoverflow.com/questions/20460769/creating-a-json-array-in-node-js – Matt Hogan-Jones May 05 '15 at 10:24

1If you want object just use object literal not array. `fruits = {}`; – Vishwanath May 05 '15 at 10:24

Is it acceptable if either `var fruits = {};` or the resulting json be `[{"name":"joy"},{"age":"12"}]` ? – user2829759 May 05 '15 at 10:25

@Vishwanath, its a dynamically creating array – Linto P D May 05 '15 at 10:27

@MattJones.Instead of looping.is there any defined function for that ? – Linto P D May 05 '15 at 10:27

@user2829759. result should be like {"name":"joy","age":"12"} – Linto P D May 05 '15 at 10:29

@LintoPD If you, as Vishwanath suggested, use `var fruits={};` instead of `var fruits=[];` then your problem should be solved – user2829759 May 05 '15 at 10:31

Fruits? And age under 21? Could you rename your variables to something else. – Aleksandr M May 05 '15 at 10:32

@user2829759.If i want to dynamically add one more item in to the array . then how can i do that – Linto P D May 05 '15 at 10:36

what do you want to do with the object generated? – Vishwanath May 05 '15 at 10:37

@Vishwanath.I need to pass this json object to client side as a function result – Linto P D May 05 '15 at 10:40

@LintoPD As you would do with array `var obj = {}; obj["foo"] = "bar";` would give `obj = { foo: 'bar' } ` – user2829759 May 05 '15 at 10:51

No, there is no predefined function in nodejs that will do it for you. But as said by the others, you can do it manually or avoid the problem by defining the array as an objet.

1@LintoPD You shoud read [Working with Objects](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Working_with_Objects) – Vishwanath May 05 '15 at 10:41

Just as you added the name and the age. Objects can be used as array in this way (I am going to get yelled at for saying that). For the example, it would be something like `var user=[]; user['name']="joy"; user['age']= "12"; /* later in the code */ user['sexe'] = "male";` – skornous May 05 '15 at 10:46
