What are the differences between the regular expressions used to replace content in vim and those in other programming languages?
I only know that the first matched group in vim is\1, which is equivalent to$1in js.

元字符 含义说明 . 匹配任意字符 \[abc\] 匹配放括号中的任意字符,也可以表示范围,例如[a-z0-9] \[^abc\] 匹配除方括号中字符的任意其他字符 \d 匹配阿拉伯数字,等同于[0-9] \D 匹配除阿拉伯数字之外的其他字符,等同于[^0-9] \x 匹配十六进制数字,等同于[0-9A-Fa-f] \X 匹配十六进制之外的任意字符,等同于[^0-9A-Fa-f] \w 匹配单词字母,等同于[0-9A-Za-z_] \W 匹配单词字母之外的任意字符,等同于[^0-9A-Za-z_] \t 匹配字符 \s 匹配空白字符,等同于[ \t] \S 匹配非空白字符,等同于[^ \t] \* 匹配0-任意个 \+ 匹配1-任意个 \? 匹配0-1个 \{n,m\} 匹配n-m个 \{n,\} 匹配n-任意个 \{,m\} 匹配0-m个 & 匹配行尾 ^ 匹配行首 \< 匹配单词词首
