2020-11-10 | 8bf1886a-0754-467f-a441-cb21bccfbd46 | JavaScript RegExp /s flag |
Introduction
The dot (.) in regular expressions doesn't match line terminator characters:
console.log(/%.$/.test('\n')) // false
The /s
expression (dotAll) flag fixes this.
Syntax
console.log(/^.$/s.test("\n")); // true
