Regular expression metacharacter # 05

The. metacharacter(wildcard)

Wildcard selects any single character. It never selects the character of the new line.

The escaping(\) metacharacter:

By using escaping metacharacters, we can limit our search for those who have value after the backslash. i.e; in the example below g. will search for the match.

const grText =
 "ABCDEFGHIJK abcdefghijk\n\t01234567890!@#$%^&()fsdfsdfdsf fsdfsdrew AB";
const newReg = new RegExp(".", "g");
const matchResult = grText.match(newReg);
console.log(matchResult);

If we want to use metacharacters inside of the character set [ ]. Then we need backslash only for four metacharacters.
