Javascript regex - how to match words after each colon in a string?

If you want to use 'Match' you should look at the following code-

const inputString = 'President: John Doe - Vice-President: Harry Arthur Blair';

// Using match with a regular expression to capture names after colons
const regex = /(?:President|Vice-President): ([^-]+)/g;
const matches = inputString.match(regex);

if (matches) {
  // Now, 'matches' array contains the names of President and Vice-President
  const [president, vicePresident] = matches.map(match => match.split(': ')[1].trim());

  console.log('President:', president);
  console.log('Vice-President:', vicePresident);
} else {
  console.log('No matches found.');
}

Bewaren a RegEx is about describing what to match and also what "no match" surroubs it.
your match starts after a colon and stops before the '-' or end if string.
You have to describe it all.
Nota: In French, "Jean-Yves" is a first compound name, since the "-" is also the end of match, you have to assume that your president can't have such name.

This avoid matching the space after 'Doe'

: ([\w]+( [\w]+)+)

Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:
perlre - perldoc.perl.org[^]
Here is links to tools to help build RegEx and debug them:

This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx: Debuggex: Online visual regex tester. JavaScript, Python, and PCRE.[^]
This site also show the Regex in a nice graph but can't test what match the RegEx: Regexper[^]
