@stdlib/assert-has-async-await-support NPM

Async/Await Support

Detect native async/await support.

Installation

npm install @stdlib/assert-has-async-await-support

Usage

var hasAsyncAwaitSupport = require( '@stdlib/assert-has-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/assert-has-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.' );
}

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
