Last Updated :

The symbol.@@toPrimitive() is an inbuilt method in JavaScript which is used to converts a given symbol object to a primitive value. Syntax:
Symbol()[Symbol.toPrimitive](hint);
Here Symbol() is the symbol object whose primitive value is to be found. Parameters: This method accepts an optional parameter “hint”.
Return value: This method returns the primitive value of the given symbol object. JavaScript code to show the working of this method.
Example-1:
javascript
const symbol1 = Symbol('Geeks');
const symbol2 = Symbol("Geeks");
const symbol3 = Symbol(123);
const symbol4 = Symbol();
let result1 = symbol1[Symbol.toPrimitive]("Value");
let result2 = symbol2[Symbol.toPrimitive]("String");
let result3 = symbol3[Symbol.toPrimitive](789);
let result4 = symbol4[Symbol.toPrimitive]();
console.log(result1);
console.log(result2);
console.log(result3);
console.log(result4);
|
Output:
> Symbol(Geeks)
> Symbol(Geeks)
> Symbol(123)
> Symbol()
In the above code, it can be seen that the optional argument “hint” can be value, string, any integer value etc. Example-2:
javascript
const symbol = Symbol('gfg');
let result = symbol[Symbol.toPrimitive];
console.log(result);
|
Output:
> function [Symbol.toPrimitive]() { [native code] }
In the above code, it can be seen that the parentheses should be used for “hint” argument otherwise it gives the result like above output. Supported Browsers:
