How to insert array into another array using javascript

Question

How to push array in another array using JavaScript?

Example:-

var a = [1,2,3,4,5]
var b = [6,7,8,9,10]
i want to push a & b into c
var c =[[1,2,3,4,5],[6,7,8,9,10]]

Please clarify: Do you want c to equal [[1,2,3,4,5],[,6,7,8,9,10]] or [1,2,3,4,5,6,7,8,9,10]? — Moob

Basically what sam said is enough:

var a = [1,2,3,4,5];
var b = [6,7,8,9,10];
var c =[];
c.push(a);
c.push(b);

To convert to JSON:

var myJsonString = JSON.stringify(yourArray);

And to get it into an object :

var arrFromJson = JSON.parse( myJsonString );

Simple, you just have to create another array to do it:

var c = [a,b];

Then, you can use .push to add more arrays.

c.push([11,12,13]);

var b = [6,7,8,9,10];
var c =[];
c.push(a);
c.push(b);

User1038 Over a year ago

and how to push c into JSON

Sam Over a year ago

What do you mean by "push into JSON"? if you want to add it to an object you can do yourObject['keyOfYourChoice']=c; and access it with yourObject['keyOfYourChoice'] or yourObject.keyOfYourChoice

Moob Over a year ago

If by "push to JSON" you mean "convert to a JSON String" you can use JSON.stringify(c) in supporting browsers
