```js
/*eslint no-undef: "error"*/

var a = someFunction();
b = 10;
var foo = someFunction();
var bar = a + 1;
```

Examples of **correct** code for this rule with `global` declaration:

```js
/*global someFunction b:writable*/
/*global someFunction, a*/
/*eslint no-undef: "error"*/

var a = someFunction();
b = 10;
var foo = someFunction();
var bar = a + 1;
```

The `b:writable` syntax in `/*global */` indicates that assignment to `b` is correct.

Examples of **incorrect** code for this rule with `global` declaration:

```js
/*global b*/
/*eslint no-undef: "error"*/

b = 10;
```

By default, variables declared in `/*global */` are read-only, therefore assignment is incorrect.

## Options

* `typeof` set to true will warn for variables used inside typeof check (Default false).
