Global pattern flags

g modifier: global. Finds all matches instead of stopping after the first

m modifier: multiline. Causes ^ and $ to match the start and end of each line, not only the start and end of the string

U modifier: Ungreedy. Quantifiers are lazy by default. A trailing ? makes a quantifier greedy
