I have a string with may have one of the 2 below structure
(w+){1}([!][a-zA-Z0-9>,]+)*([#]d+)?
(w+){1}([#]d+)?([!][a-zA-Z0-9>,]+)*
some examples would be
"Abc1!deF2>Ghi3,4jlmNO!pQr5st#1400" "Abc1#1400!deF2>Ghi3,4jlmNO!pQr5st"
The goal is to match as below
["Abc1", "!deF2>Ghi3,4jlmNO", "!pQr5st", "#1400"] ["Abc1", "#1400", "!deF2>Ghi3,4jlmNO", "!pQr5st"]
I can manage to get the result with 3 regex, but not with 1
const a = str.match(/w+/) const b = str.match(/([!][a-zA-Z0-9>,]+)/g) const c = str.match(/[#]d+/)
How can I get the expected result with a single regex ?

Answer
Maybe use | to separate possible matches:
const regExp = /w+|![a-zA-Z0-9>,]+|#d+/g;
console.log("Abc1!deF2>Ghi3,4jlmNO!pQr5st#1400".match(regExp));
console.log("Abc1#1400!deF2>Ghi3,4jlmNO!pQr5st".match(regExp));Also note that (w+){1} is equivalent to w+, and [!] and [#] are the same as ! and # respectively.
