Which of those codes works faster?

I need to know which of those 2 codes works faster. The main difference is that in 2nd code I'm using hasownproperty https://code.sololearn.com/WO8yGcyVqF9G/?ref=app https://code.sololearn.com/WvxODIW4Unw7/?ref=app

You are talking about nanoseconds or possibly picoseconds difference, which can be hardly measured in a single operation. If you wonder about such performance differences, you might feel something when you deal with millions of data points, otherwise it is negligible. I found for you a benchmark which will show the difference between some of the object lookup methods: https://measurethat.net/Benchmarks/Show/977/0/undefined-vs-typeof-vs-in-vs-hasownproperty According to this, your first code (bool method, that checks the existence of a property) is very slightly faster than using hasownproperty.
