Building the addTransactionToPendingTransactions method 

Next, we need to push the newTransaction that was returned to the pendingTransactions array of the blockchain. Therefore, let's create another method, called addTransactionToPendingTransactions:

3. Then, we simply want to return the index of the block to which the ...
