@stdlib/assert-has-symbol-support

What is @stdlib/assert-has-symbol-support?

@stdlib/assert-has-symbol-support is a package that allows you to check if the runtime environment supports ES6 symbols. This can be useful for ensuring compatibility and feature detection in JavaScript applications.

What are @stdlib/assert-has-symbol-support's main functionalities?

Check Symbol Support

This feature allows you to check if the current environment supports ES6 symbols. The function returns a boolean value indicating the presence or absence of symbol support.

const hasSymbolSupport = require('@stdlib/assert-has-symbol-support');

if (hasSymbolSupport()) {
  console.log('Symbols are supported.');
} else {
  console.log('Symbols are not supported.');
}

Other packages similar to @stdlib/assert-has-symbol-support

has-symbols

The 'has-symbols' package checks for native Symbol support in the runtime environment. It provides similar functionality to @stdlib/assert-has-symbol-support by returning a boolean value indicating whether symbols are supported.

is-symbol

The 'is-symbol' package checks if a given value is a symbol. While it does not directly check for symbol support in the environment, it can be used in conjunction with other packages to achieve similar goals.

core-js

The 'core-js' package is a comprehensive polyfill library that includes support for ES6 symbols among many other features. It can be used to ensure compatibility across different environments, but it is more heavyweight compared to @stdlib/assert-has-symbol-support.

About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Symbol Support

Detect native Symbol support.

Installation

npm install @stdlib/assert-has-symbol-support

Usage

var hasSymbolSupport = require( '@stdlib/assert-has-symbol-support' );

hasSymbolSupport()

Detects if a runtime environment supports ES2015 Symbol.

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

Examples

var hasSymbolSupport = require( '@stdlib/assert-has-symbol-support' );

var bool = hasSymbolSupport();
if ( bool ) {
    console.log( 'Environment has Symbol support.' );
} else {
    console.log( 'Environment lacks Symbol 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.
