相当于变量不能在定义前使用。看下面的例子就明白了

// TypeError: undefined is not a function
functionOne();

var functionOne = function() {
  console.log(“Hello!”);
};

// Outputs: “Hello!”
functionTwo();

function functionTwo() {
  console.log("Hello!");
}

不错。 看了下还支持key binding。 Vi党 Emacs党的福音。之前Vi都是通过设置.inputrc来自定义mysql。set editing-mode vi

执行下 SET PASSWORD = PASSWORD('new_password');

参考: https://dev.mysql.com/doc/refman/5.6/en/alter-user.html

mysql> SELECT 1;
ERROR 1820 (HY000): You must SET PASSWORD before executing this statement
\mysql> SET PASSWORD = PASSWORD('new_password');
Query OK, 0 rows affected (0.01 sec)

git pull origin branch_name

相当于

git fetch origin branch_name
git merge branch_name

默认执行了下merge操作。
