Test String: The text where you want to find matches. Flags: Global (g) Find all matches, not just the first. Ignore Case (i) Perform case-insensitive matching. Multiline (m) Treat start and end anchors (^ and $) as matching at the start/end of each line, not just the whole string. DotAll (s) Allows dot (.) to match newline characters. Unicode (u) Treat pattern as a sequence of Unicode code points. Sticky (y) Matches only from the index indicated by the `lastIndex` property of this regular expression in the target string.
