@stdlib/assert-has-tostringtag-support
Advanced tools
@stdlib/assert-has-tostringtag-support is a package that allows you to check if the environment supports the `Symbol.toStringTag` property. This property is used to customize the default string description of objects.
Check for Symbol.toStringTag support
This feature allows you to check if the current JavaScript environment supports the `Symbol.toStringTag` property. The code sample demonstrates how to use the package to perform this check and log the result.
const hasToStringTagSupport = require('@stdlib/assert-has-tostringtag-support');
if (hasToStringTagSupport()) {
console.log('Environment supports Symbol.toStringTag');
} else {
console.log('Environment does not support Symbol.toStringTag');
}The `has-symbols` package checks if the environment supports ES6 symbols, including `Symbol.toStringTag`. It provides a broader check for symbol support compared to `@stdlib/assert-has-tostringtag-support`, which is specifically focused on `Symbol.toStringTag`.
The `is-symbol` package checks if a given value is a symbol. While it does not directly check for `Symbol.toStringTag` support, it can be used in conjunction with other checks to determine symbol-related capabilities in the environment.
The `has-tostringtag` package specifically checks for the presence of the `Symbol.toStringTag` property in the environment. It is very similar to `@stdlib/assert-has-tostringtag-support` in terms of functionality.
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!
Detect native

Detects if a runtime environment supports ES2015 Symbol.toStringTag.
var bool = hasToStringTagSupport();
// returns <boolean>
var hasToStringTagSupport = require( '@stdlib/assert-has-tostringtag-support' );
var bool = hasToStringTagSupport();
if ( bool ) {
console.log( 'Environment has `toStringTag` support.' );
} else {
console.log( 'Environment lacks `toStringTag` support.' );
}
@stdlib/assert-has-tostringtag-support-cli: CLI package for use as a command-line utility.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.
