I want to match Dog - 狗, Fish - 鱼... my regular expression is: const reg = /(.*)\s*-\s*(.*),/g , but the result is not what i expect.so how to write a correct one?

my final answer is [[Dog,狗],[Cat,猫],...] ,I know I should use regular expression, but it has trouble

Answer 1

You can use

/(\S+)[\s\u200B]*-[\s\u200B]*([^,]*)/g

See the regex demo .

Details :

• (\S+) - Group 1: one or more non-whitespace chars
• [\s]* - zero or more whitespaces or ZWJ symbol
• - - a hyphen
• [\s]* - zero or more whitespaces or ZWJ symbol
• ([^,]*) - Group 2: zero or more chars other than a comma.
