title: JavaScript RegExp /s flag
---
# Introduction
The dot (.) in regular expressions doesn't match line terminator
characters:
``` javascript
console.log(/%.$/.test('\n')) // false
```
The `/s` expression (dotAll) flag fixes this.
# Syntax
``` javascript
console.log(/^.$/s.test("\n")); // true
```
