JavaScript BigInt is an inbuilt object in JavaScript that provides a way to represent whole numbers larger than 253-1 which is the largest number that can represent with the Number primitive. It is represented by the MAX_SAFE_INTEGER constant.
Example: This example creates a BigInt by appending n at the end of the number.
Javascript
let bigNum = 123422222222222222222222222222222222222n
console.log(bigNum)
let bigHex = 0x1ffffffeeeeeeeeefn
console.log(bigHex)
let bigBin = 0b1010101001010101001111111111111111n
console.log(bigBin)
|
Output:
123422222222222222222222222222222222222n
VM41:6 36893488074118328047n

Constructor |
Descriptions |
Example |
BigInt() |
Convert any primitive data type or object to a BigInt data type. |
|
JavaScript BigInt Properties: A JavaScript property is a member of an object that associates a key with a value.
- Instance Property: An instance property is a property that has a new copy for every new instance of the class.
Instance Properties |
Descriptions |
Example |
constructor |
Return the bigInt constructor function for the object. |
|
JavaScript BigInt Methods: Methods are actions that can be performed on objects.
- Static Method: If the method is called using the BigInt class itself then it is called a static method of BigInt.
Static Methods |
Descriptions |
Example |
asIntN() |
Wrap a BigInt value to a signed integer between -2width-1 and 2width-1-1. |
|
asUintN() |
Wrap a BigInt value to an unsigned integer between 0 and 2width-1. |
|
- Instance Method: If the method is called on an instance of a number then it is called an instance method.
Instance Methods |
Descriptions |
Example |
toLocaleString() |
Return a string with a language-sensitive representation of this BigInt. |
|
toString() |
Return a string representing the specified BigInt object. |
|
valueOf() |
