Async/Await Support

Detect native async/await support.

Usage

var hasAsyncAwaitSupport = require( '@stdlib/utils/detect-async-await-support' );

hasAsyncAwaitSupport()

Detects if a runtime environment supports ES2017 async/await.

var bool = hasAsyncAwaitSupport();
// returns <boolean>

Notes

  • The implementation uses code evaluation, which may be problematic in browser contexts enforcing a strict content security policy (CSP).

Examples

var hasAsyncAwaitSupport = require( '@stdlib/utils/detect-async-await-support' );

var bool = hasAsyncAwaitSupport();
if ( bool ) {
    console.log( 'Environment has native async/await support.' );
} else {
    console.log( 'Environment lacks native async/await support.' );
}
