# Proxy Support
> Detect native [`Proxy`][mdn-proxy] support.
## Usage
```javascript
var hasProxySupport = require( '@stdlib/assert/has-proxy-support' );
```
#### hasProxySupport()
Detects if a runtime environment supports ES2015 [`Proxy`][mdn-proxy].
```javascript
var bool = hasProxySupport();
// returns
```
## Notes
- The implementation uses code evaluation, which may be problematic in browser contexts enforcing a strict [content security policy][mdn-csp] (CSP).
## Examples
```javascript
var hasProxySupport = require( '@stdlib/assert/has-proxy-support' );
var bool = hasProxySupport();
if ( bool ) {
console.log( 'Environment has native Proxy support.' );
} else {
console.log( 'Environment lacks native Proxy support.' );
}
```
