Description

The Minifier not generating the script when BigInt() method is used with a higher values.

Steps to recreate

Adding a sample code. The intention of this code is to check if the given string is well within the C# Int64 range.
let TryParseLong = function (str, defaultValue) {
var retValue = defaultValue;
if (str !== null) {
if (str.length > 0 && str.length <= 19) {
if (!isNaN(str)) {
if (BigInt(str) < BigInt("9223372036854775807")) { //Int64.MaxValue is "9223372036854775807"
retValue = BigInt(str);
}
console.log(retValue);
}
}
}

return retValue;

}

Current behavior

The minifier generates the minification file
However the BigInt("9223372036854775807") gets generated as -9223372036854775808n

The minified code generated on the machine is
let TryParseLong=function(n,t){var i=t;return n!==null&&n.length>0&&n.length<=19&&(isNaN(n)||(BigInt(n)<-9223372036854775808n&&(i=BigInt(n)),console.log(i))),i},a=123456,b=TryParseLong(a,-1);alert(b);

Expected behavior

Ideally it should stay as
9223372036854775808n

let TryParseLong=function(n,t){var i=t;return n!==null&&n.length>0&&n.length<=19&&(isNaN(n)||(BigInt(n)<9223372036854775808n&&(i=BigInt(n)),console.log(i))),i},a=123456,b=TryParseLong(a,-1);alert(b);

Is this supported by NUglify?

[failwyn]

This is caused by targeting .Net 3.5 in NUglify; if you use BigInt("9007199254740991") for your comparison, it works correctly; if you aren't expecting numbers to be larger than that.
