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
|
|
```
