Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2020.

valueOf() 方法返回 BigInt 对象包装的原始值。

尝试一下 
console.log(typeof Object(1n));
// Expected output: "object"

console.log(typeof Object(1n).valueOf());
// Expected output: "bigint"
语法 
bigIntObj.valueOf()
返回值

表示指定 BigInt 对象的原始 BigInt 值。

示例 Using valueOf

js

typeof Object(1n); // object
typeof Object(1n).valueOf(); // bigint
