@@PD_Patrice person is the argument passed to the function that will be executed for each element of the people array, and it represents each individual element of the array during each iteration. You can just name it anything you like though.
Salutare. de ce la minutul 3:45 (apx), in linia 3 ai scris ' nums', si nu Numbers? Inteleg rezultatul unde trebuie sa duca codul, dar nu inteleg de ce trebuie scris asa.
I guess the reason its not common to use filter for removing duplicates is that it involves nesting an indexOf loop inside a filter loop, which maybe considered a bad practice for time complexity.
hey. Thanks for the explanation! Its being super helpful for a beginner like me :) One question, where did you get "person" from? There is no person in the adults arrays, so im trying to understand how to access person.age, if there's no person. Thank you!
Hello Florin pop thx for your video but i want ask if i have array of objects and i want get the duplicate objects with filter function how i can do it
Check out the other videos in the JavaScript Array Methods series: th-cam.com/play/PLgBH1CvjOA62PBFIDq55-S6Beivje30A2.html
That is a clever way of removing duplicates using the filter method Florin. I've never seen it done that way. I writing that down haha.
Better do it with Set 😆
@@FlorinPop Yeah that's how I do it usually, but I like to know multiple ways of doing the same thing as you well know haha
Thank you sir for the last use case of filter method(removing duplicates),i never thought it that way,thanks for the eye opener.
Your welcome. Although whenever you want to remove duplicates, I’d suggest you use Set.
Thank you! Just what I needed.
thanks. this helped me with my project 🙂
amazing usecases. thanks
Great video, I only have 1 question. In 2:30 where did the "person" variable come from?
Do you know the answer to this? I'm just starting out and I'm SO confused by this concept...

Another excellent explanation, thanks Florin
Thanks you Florin for helping me understand these concepts 🙆
Do you understand JavaScript now?
Thankyou Florin!
How you are outputting console.log in terminal? Is there any extension for it? Thank you for the video.
I use nodemon to run the script on saving the file.
Florin Pop Thank you much man! Best of luck for the future.
thanks for sharing informative things

Yup. Plus it’s easier with Set
Good because that last part was a little confusing.
