regex to get multiple values in javascript

my string is

Cuenta de Ahorros | 1231231231 Bs 102,423.88 Cuenta de Ahorros | 1231233123 Usd 102,423.88 Cuenta de Ahorros | 87316633 Usd 10.233 Cuenta de Ahorros | 49189387113313 Usd 12.301

but using match() i can’t capture all string values

const strings = [
  "Cuenta de Ahorros | 1231231231 Bs 102,423.88 Cuenta de Ahorros | 1231233123 Usd 102,423.88 Cuenta de Ahorros | 87316633 Usd 10.233 Cuenta de Ahorros | 49189387113313 Usd 12.301"
]; 

let pattern = /(?<=Bs).*?(?=Cuenta)/;
strings.forEach((s) => {
  console.log(s.match(pattern));
});

returns only

[" 102,423.88 ", 40, "Cuenta de Ahor…] 0 : " 102,423.88 "

i need result like

Bs 102,423.88

Usd 102,423.88

Usd 10.233

Usd 12.301

>Solution :

You can use

const strings = [
  "Cuenta de Ahorros | 1231231231 Bs 102,423.88 Cuenta de Ahorros | 1231233123 Usd 102,423.88 Cuenta de Ahorros | 87316633 Usd 10.233 Cuenta de Ahorros | 49189387113313 Usd 12.301"
]; 

let pattern = /\b(?:Bs|Usd)\b.*?(?=\s*Cuenta\b|$)/gi;
strings.forEach((s) => {
  console.log(s.match(pattern));
});

See the regex demo.

Pattern details:

• \b(?:Bs|Usd)\b – a whole word Bs or Usd
• .*? – any zero or more chars other than line break chars, as few as possible
• (?=\s*Cuenta\b|$) – a positive lookahead that requires (immediately to the right of the current location) either zero or more whitespaces and then a whole word Cuenta (\s*Cuenta\b|$), or end of string ($).

I added g flag and used String#match to extract all matches from a string, and i flag makes the search case-insensitive.
