I don't believe this should be labeled easy. Sure the solution is easy enough to implement, but getting to the correct solution requires trial and error and research. Should be a medium question.

Would you not want to change a.length < 53 to (a.length +b.length) <53 . Since you are adding numbers wouldn't you have to be afraid that the added numbers are going to break the max safe integer size?

var addBinary = function(a, b) {
let sum =0

if(a.length+b.length < 53){
return sum = (parseInt(a, 2)+parseInt(b, 2)).toString(2)
}else{
sum = BigInt("0b"+a) +BigInt("0b"+b)
return sum.toString(2)
}

};
