has-to-string-tag-x
Advanced tools
The has-to-string-tag-x npm package is a utility that checks if an object has the `@@toStringTag` property. This property is used to customize the default string description of an object.
Check if an object has a toStringTag property
This feature allows you to check if an object has the `@@toStringTag` property. In the example, the object `obj` has a custom `toStringTag` property, so the function returns `true`.
const hasToStringTag = require('has-to-string-tag-x');
const obj = { [Symbol.toStringTag]: 'Custom' };
console.log(hasToStringTag(obj)); // true
Check if an object does not have a toStringTag property
This feature allows you to check if an object does not have the `@@toStringTag` property. In the example, the object `obj` does not have a `toStringTag` property, so the function returns `false`.
const hasToStringTag = require('has-to-string-tag-x');
const obj = {};
console.log(hasToStringTag(obj)); // false
The has-symbols package checks if the runtime environment supports ES6 symbols, which includes the `@@toStringTag` symbol. While it does not specifically check for the presence of the `@@toStringTag` property on an object, it is useful for determining if symbols can be used in the environment.
The is-symbol package checks if a given value is a symbol. This can be used in conjunction with other utilities to determine if an object has a `@@toStringTag` property by checking if the property key is a symbol.
The get-intrinsic package provides access to ECMAScript intrinsic objects, including `Symbol.toStringTag`. It can be used to retrieve the `@@toStringTag` symbol and check if an object has this property.
