How to get Collection value inside javascript.

Thanks Vikas,

Sorry, I am asking out of subject question. How can I access logged in user roles.

You need to hit the endpoint if you want to get these roles in JS. 
Here is the API

select rank.simple_criteria from users where id='777'

Thanks Vikas, I have made couple of web service call (Both v1 and v2) to get the data and this is what I have followed:

For V1:

URL:

http://api.lithium.com/community/v1/<Tenant_id>/users/id/2/roles?restapi.response_format=json

Header:

Client-id: <CLIENT ID>

Authorization: Bearer <TOKEN>

Content-type: application/json

For V2:

https://api.lithium.com/community/2.0/<Tenant_Id>/search?q=select+*+from+roles+where+users%2Eid%3D%272%27

Header:

Client-id: <CLIENT ID>

Authorization: Bearer <TOKEN>

Content-type: application/json

Do i need to implement the same in javascript or please point to an example how this can be implemented using javascript.
