Subsocial Playground helps you run different code snippets from Subsocial SDK without downloading it.
To use the SDK, open this link in new tab.
On the left side, the sidebar contains a list of code snippets that you might need while building your own dapp on Subsocial.
Press the "Run" button to see output.
There are a couple of inbuilt functions provided to help you focus on the main code snippet.
Read the docs to see more details.
