Getting the ABI and Bytecode of the Contract

Now that the contract has been tested to work correctly, it is time to test it on a real blockchain. But before you do it, there is something else you need to understand. When a contract is compiled, there are two items of interest:ABI (application binary interface) – The ABI is a JSON string that describes the makeup of the contract – the functions as well as the parameter types of each function.

Bytecode – When a contract is compiled, it is compiled into opcodes (think of opcode as the assembly language for your computer). Each opcode has its hexadecimal counterparts. The bytecode is basically a collection of each opcode’s hexadecimal representation.
