RegExp.prototype.global

## Description

`RegExp.prototype.global` has the value `true` if the `g` flag was used; otherwise, `false`. The `g` flag indicates that the regular expression should be tested against all possible matches in a string. Each call to [`exec()`](/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp/exec) will update its [`lastIndex`](/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp/lastIndex) property, so that the next call to `exec()` will start at the next character.

Some methods, such as [`String.prototype.matchAll()`](/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/matchAll) and [`String.prototype.replaceAll()`](/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replaceAll), will validate that, if the parameter is a regex, it is global. The regex's [`[Symbol.match]()`](/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp/Symbol.match) and [`[Symbol.replace]()`](/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp/Symbol.replace) methods (called by [`String.prototype.match()`](/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/match) and [`String.prototype.replace()`](/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace)) would also have different behaviors when the regex is global.

The set accessor of `global` is `undefined`. You cannot change this property directly.

## Examples

### Using global

```js
const globalRegex = /foo/g;

const str = "fooexamplefoo";
console.log(str.replace(globalRegex, "")); // example

const nonGlobalRegex = /foo/;
console.log(str.replace(nonGlobalRegex, "")); // examplefoo
