BigInt - JavaScript - MDN Web Docs
The resulting primitive is then converted to a BigInt. The best way to achieve nearly the same effect in JavaScript is through the BigInt() function: BigInt(x) uses the same algorithm to convert x, except that Numbers don't throw a TypeError, but are converted to BigInts if they are integers.

September 21, 2020 - Polyfilling bigints is tricky. The reason is that many JavaScript operators, such as +, - and so on behave differently with bigints compared to regular numbers. For example, division of bigints always returns a bigint (rounded if necessary).

What is a BigInt in JavaScript?
Take a look at the example below to see why BigInt is needed. var maxIntNum = 9007199254740991; var largeNumber = maxIntNum + 2; // 9007199254740992 · The expected result for the above operation is 9007199254740993, but we get 9007199254740992.

BigIntis a built-in object that provides a way to represent whole numbers larger than 2^53 - 1, which is the largest number JavaScript can reliably represent with theNumberprimitive and represented by theNumber.MAX_SAFE_INTEGERconstant.BigIntcan be used for arbitrarily large integers.
Difference:
BigIntcannot be used with methods in the built-inMathobject and cannot be mixed with instances ofNumberin operations- Because coercing between
NumberandBigIntcan lead to loss of precision, it is recommended to only useBigIntwhen values greater than 2^53 are reasonably expected and not to coerce between the two types.

The differences between BigInt and Number:
Number |
BigInt |
|
|---|---|---|
| Safe Range | Number.MAX_SAFE_INTEGER; loses precision outside of this range |
Extremely large integers |
| Math operations | Supports the Math object |
Basic arithmetic operations: + * - % ** |
| Decimal vs. Integer support | Integers and decimals, e.g 1.00, 2.56 |
Only integers, e.g 1n, 2n. 5n / 2 === 2n |
| Syntax | No special syntax | Append n to the end of a number literal or use new BigInt('100') |
| Type Conversion | Automatically converts Number to BigInt in operations |
Requires explicit conversion to Number for arithmetic involving Number values |
| JSON | Supported by default | Not serializable by default |
Use BigInt when you need to work with extremely large integers or require precise integer arithmetic without any loss of precision.

July 22, 2019 - Consider the following example: ... The result of this expression is outside of the domain of both BigInt and Number. A Number with a fractional part cannot be accurately converted to a BigInt. And a BigInt larger than 253 cannot be accurately converted to a Number. As a result of this restriction, it’s not possible to perform arithmetic operations with a mix of Number and BigInt operands. You also cannot pass a BigInt to Web APIs and built-in JavaScript functions that expect a Number.
