    // Switch dot with comma and vice versa
    return (match == ',') ? '.' : ',';
  }

  // Replace all occurrences of either dot or comma.
  // Use function switcher to decide what to replace them with.
  return s.replaceAll(/\.|\,/g, switcher);

s.replace(/(?<=\d)[\s.]+(?=\d)/g, '')

See the regex demo.

Details

• (\d) - Group 1 ($1 in the replacement pattern is the value of the group): a digit
• [\s.]+ - one or more whitespace or . chars
• (?=\d) - a positive lookahead that ensures the next char is a digit.

See JavaScript demo:

const text = 'This is an 8-string 12.34.5678; and this is another 13-string 1234 5678 9123 0 okay?';
console.log(text.replace(/(\d)[\s.]+(?=\d)/g, '$1'));
