Two Functions in solidity| Importance to Contract creation.

[Wenbing]

I found these lines of code in solidity. As I know solidity is the major programming language of the etheruem Blockchain network.

Here are some functions I want the house to shed light on.

What do they really mean when the codes are implemented.

1.Msg.sender

2.Msg.value

Do we have other smart contract creation programming languages aside from solidity?

We have a lot of smartcontract programming languages aside from solidity and here's the list

This list contains 40 smartcontract platforms complete with what kind of programming language that used by those smartcontracts.

In your personal experience and opinion, which of the programming language is the best in terms of functions and less bugs.
