问题描述

我正在做一些红宝石练习，它说我需要返回并用+=速记符号重写脚本.

I am doing some ruby exercises and it said I need to go back and rewrite the script with += shorthand notations.

此练习主要涉及学习新方法.问题是，我不知道+=在尝试在线查找时意味着什么.

This exercise deals primarily with learning new methods. The problem is, I have no idea what += means when I tried to look it up online.

+=是简写运算符.

someVar += otherVar

与

someVar = someVar + otherVar
