Global
By default, as soon as a regular expression finds a match within a string, it stops looking. The global flag tells the regular expression to find all matches in the string, not just the first. To set the global flag, you place a g outside the closing forward slash of your regular expression: /[0-9]{4}/g finds all years in a string, not just the first one.
