How to write a regular expression using a repetition quantifier to capture all names and values in a URL query string like this: User=Jack&Age=&City=Paris?

The "0 or more times" repetition quantifier allows us to repeat a pattern unit 1 or more times in the matching process. The "0 or more times" repetition quantifier character is '*' and it needs be placed immediately after the pattern unit. For example:
/^ */ # matches any number of leading space characters / *$/ # matches any number of trailing space characters
The regular expression to capture all names and values in a URL query string is:
([^=]+)=([^&]*)
([^=]+) - repeats 1 more times on any non '=' characters
= - matches the '-'
([^&]*) - repeats any number of times on any non '&' characters
