为什么是一个等于号？

Why an equals sign?

Scala把主体之前的部分包含等于号作为函数定义，而一个函数在函数式编程中永远都有返回值。

Scala regards a method with the equals sign before the body as a function definition and a function always returns a value in functional programming.

使用单等于号来向变量赋值，而不是像在前一个条件中那样使用双等于号 (==) 来比较值。

Use the single equal sign to assign a value to a variable, unlike the double equal sign (==), as in the previous condition, which compare the values.
