Regular Expression Modifiers

The modifiers are optional modifiers that affect the way the pattern is matched.

g: The g modifier matches the pattern globally, which means that it matches the pattern in the entire string.
i: The i modifier makes the pattern case-insensitive.
m: The m modifier matches the pattern across multiple lines.

You can add modifiers by appending them to the regular expression.

let regex = /pattern/gi;

This regex will perform a global, case-insensitive search for “pattern.”
