# isAbsolutePath
> Test if a value is an absolute path.
## Usage
```javascript
var isAbsolutePath = require( '@stdlib/assert/is-absolute-path' );
```
#### isAbsolutePath( value )
Tests if a `value` is an absolute path.
```javascript
var IS_WINDOWS = require( '@stdlib/assert/is-windows' );
var bool;
if ( IS_WINDOWS ) {
bool = isAbsolutePath( 'C:\\foo\\bar\\baz' );
// returns true
} else {
bool = isAbsolutePath( '/foo/bar/baz' );
// returns true
}
```
#### isAbsolutePath.posix( value )
Tests if a `value` is a POSIX absolute path.
```javascript
var bool = isAbsolutePath.posix( '/foo/bar/baz' );
// returns true
bool = isAbsolutePath.posix( 'foo/bar/baz' );
// returns false
```
#### isAbsolutePath.win32( value )
Tests if a `value` is a Windows absolute path.
```javascript
var bool = isAbsolutePath.win32( 'C:\\foo\\bar\\baz' );
// returns true
bool = isAbsolutePath.win32( 'foo\\bar\\baz' );
// returns false
```
## Notes
- `isAbsolutePath()` is platform-specific. On Windows platforms, the function is equal to `isAbsolutePath.win32()`. On POSIX platforms, the function is equal to `isAbsolutePath.posix()`.
## Examples
```javascript
var isAbsolutePath = require( '@stdlib/assert/is-absolute-path' );
var bool = isAbsolutePath.posix( '/foo/bar/baz' );
// returns true
bool = isAbsolutePath.posix( '/foo/..' );
// returns true
bool = isAbsolutePath.posix( 'foo/' );
// returns false
bool = isAbsolutePath.posix( 'foo' );
// returns false
bool = isAbsolutePath.posix( '.' );
// returns false
bool = isAbsolutePath.posix( '' );
// returns false
bool = isAbsolutePath.win32( 'C:\\foo\\bar\\baz' );
// returns true
bool = isAbsolutePath.win32( '//server' );
// returns true
bool = isAbsolutePath.win32( '\\\\server' );
// returns true
bool = isAbsolutePath.win32( 'C:/foo/bar/baz' );
// returns true
bool = isAbsolutePath.win32( '/foo/..' );
// returns true
bool = isAbsolutePath.win32( 'foo\\bar\\baz' );
// returns false
bool = isAbsolutePath.win32( 'foo/bar/baz' );
// returns false
bool = isAbsolutePath.win32( 'foo/..' );
// returns false
bool = isAbsolutePath.win32( '.' );
// returns false
bool = isAbsolutePath.win32( '' );
// returns false
```
