How to get ethereum contract public variables?

Question

I want to get bool paused; in my react application without transaction. It is implemented in myetherwallet.com contract gui. How can i do this? If possible i want to do this with mappings too.

Answer 1

You need to use the call method; it is evaluated directly on local node without sending transaction to the blockchain.
