BLOCKED - BigInt literals fail - Error: Line 37: Unexpected token ILLEGAL

[manoharreddyporeddy]

BigInt literals like 1n, 10n fail. However, BigInt(1), BigInt(10) pass.

Steps to reproduce

Below are both Fail code that throws the error, and converted code Pass code that passes.

// Fail code
function factorial(n) {
    return n !== 1n ? n * factorial(n - 1n) : 1n;
}

// Pass code
function factorial(n) {
    return n !== BigInt(1) ? n * factorial(n - BigInt(1)) : n;
}

Expected output

Fail code should pass. Changing all "1n" to "BigInt(1)" is frustrating, mainly not feasible to do in a project.

Actual output

BigInt literals like 1n, 10n fail throws below error:

Error: Line 37: Unexpected token ILLEGAL
