JavaScript Regular Expression modifiers

Regular expressions are typically used for two string methods:

The search () method retrieves the string specified in the string, or retrieves a substring that matches the regular expression and returns the starting position of the substring.

The replace () method is used to replace other characters with some characters in a string, or to replace a substring that matches a regular expression.

Regular expression modifiers

Modifiers can be case insensitive in global search:

I: Perform a case insensitive match

G: Performs a global match (finds all matches rather than stops after the first match is found)

M: Perform multi-line matching
