Regex Flags

Flags are used to modify the behavior of a regex pattern. Flags are also known as modifiers. They determine whether the pattern is case-sensitive, multi-line, etc.

Global Flag

The global flag /g is used to search for all occurrences of a pattern in a string.

For example, the regex pattern /go/g matches all occurrences of go in a string.

Case-Insensitive Flag

The case-insensitive flag /i is used to perform a case-insensitive search.

For example, the regex pattern /go/i matches go, Go, and GO.

Multi-Line Flag

The multi-line flag /m is used to perform a multi-line search.

For example, the regex pattern /^go/m matches go at the start of each line.
