After grouping:

Regular expression: Rep =/\bwu (\w*) b/

Rep.exec (' wuli_48_hong_34 ') #t [' Wuli ', ' Li ']

Global match

Regular expression: Rep =/\bwu\w*b/g Plus g

Rep.exec (' wuli_48_wung_34 ') #执行第一次 [' Wuli ']

Rep.exec (' wuli_48_wung_34 ') #执行第二次 [' Wung ']

　　　　　　　　　

1. Define Regular expressions

• /.../for defining regular expressions
• /.../g represents a global match
• /.../i indicates case insensitive
• /.../m for multi-line matching
  JS regex matches itself to support multiple lines, where multiple lines match only affect the regular expression ^ and $,m mode will also use ^$ to match the contents of the newline)
