### immutable

`immutable`变量可以在声明时或构造函数中初始化，因此更加灵活。在`Solidity v8.0.21`以后，`immutable`变量不需要显式初始化。反之，则需要显式初始化。
`immutable`变量可以在声明时或构造函数中初始化，因此更加灵活。在`Solidity v8.0.21`以后，`immutable`变量不需要显式初始化，未显式初始化的`immutable`变量将使用数值类型的初始值（见 [8. 变量初始值](https://github.com/AmazingAng/WTF-Solidity/blob/main/08_InitialValue/readme.md#%E5%8F%98%E9%87%8F%E5%88%9D%E5%A7%8B%E5%80%BC)）。反之，则需要显式初始化。
若`immutable`变量既在声明时初始化，又在constructor中初始化，会使用constructor初始化的值。

``` solidity
// immutable变量可以在constructor里初始化，之后不能改变
uint256 public immutable IMMUTABLE_NUM = 9999999999;
address public immutable IMMUTABLE_ADDRESS;
// 在`Solidity v8.0.21`以后,下列变量数值暂为初始值
address public immutable IMMUTABLE_ADDRESS;
uint256 public immutable IMMUTABLE_BLOCK;
uint256 public immutable IMMUTABLE_TEST;

`selfdestruct`是智能合约的紧急按钮，销毁合约并将剩余`ETH`转移到指定账户。当著名的`The DAO`攻击发生时，以太坊的创始人们一定后悔过没有在合约里加入`selfdestruct`来停止黑客的攻击吧。在坎昆升级后，`selfdestruct`的作用也逐渐发生了改变，什么都不是一成不变的，还是要保持学习。
