Ruby 是否有一个 string.startswith(“abc") 内置方法? [英] Does Ruby have a string.startswith("abc") built in method?

问题描述

Ruby 有内置的 some_string.starts_with("abc") 方法吗?

Does Ruby have a some_string.starts_with("abc") method that's built in?

推荐答案

它叫做 String#start_with?，而不是 String#startswith:在 Ruby 中，布尔型方法的名称以 ? 和方法名称中的单词用 _ 分隔.不确定 s 去哪里了，我个人更喜欢 String#starts_with? 而不是实际的 String#start_with?

It's called String#start_with?, not String#startswith: In Ruby, the names of boolean-ish methods end with ? and the words in method names are separated with an _. Not sure where the s went, personally, I'd prefer String#starts_with? over the actual String#start_with?
