assignment statement expression

基本解释

Another, more compact way to represent the same expression is to use an assignment statement similar to this
另一种更紧凑的表达方式是使用下面这样的赋值语句
In writing an assignment statement, for example, you can declare variables of any type, use any identifier to the left of the equal sign, and supply any expression on the right.
例如你要写一句赋值语句，你可以声明任何类型的变量，在等号的左边使用任何标识符，然后在右边给出任何的表达式。
The value of the property participates in the expression just as a variable or constant would, or it is stored in the variable or property on the left side of the assignment statement.
属性值会如同变数或常数参与运算式的方式参与运算式，或是储存于指派陈述式左边的变数或属性中。
