Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.
@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.

} else {
console.log( 'Environment lacks `toStringTag` support.' );
}
