Is OAuth authorization possible in a browser without a Client Secret?

Question

JavaScript

Is it possible to authorize a client via OAuth using only a browser?
I connect authorization through social networks using javascript, everything should work in the browser, so the Client Secret is not used for security purposes.
This feature is described in the standard, but I did not manage to implement it in popular social networks.
Perhaps someone faced a similar task, share an example or a link to a working site.

There is an OAuth Implicit Flow for this.
Here is the description for VK: https://vk.com/dev/implicit_flow_user
