Symbol.prototype[@@toPrimitive]

The [@@toPrimitive]() method converts a Symbol object to a primitive value.

Syntax

Symbol()[Symbol.toPrimitive](hint);

Return value

The primitive value of the specified Symbol object.

Description

The [@@toPrimitive]() method of Symbol returns the primitive value of a Symbol object as a Symbol data type. The hint argument is not used.

JavaScript calls the [@@toPrimitive]() method to convert an object to a primitive value. You rarely need to invoke the [@@toPrimitive]() method yourself; JavaScript automatically invokes it when encountering an object where a primitive value is expected.
