Master JavaScript Objects

#javascript #object #software #webdevelopment

Hello, I am back with a new video.

Objects and Object-oriented programming in JavaScript are complex topics with a lot of information to know, it usually takes days to learn about objects. So the goal of this video is to compact days of training into a few minutes. You will learn about objects, properties, attributes, inheritance, prototype and constructors. You will learn about Classes in my next video!

21:58 Constructors
27:12 Conclusion

A few notes:
- Prerequisites: you should know about JavaScript variables & functions, prior knowledge in objects is not required but will help
- I tried to make the video beginner friendly while still talking about advanced concepts, some parts may be a bit difficult
- Some explanations (like how the new operator works) should be considered “mental model” more than what’s really happening, reading the specification being difficult and the actual implementation being engine-dependent, I created some approximations/representations that can be considered inaccurate
- Some part of the audio are a bit scuffed, I re-recorded some part with a different set up
- My pronunciation & voice are not the best, I could pay someone to read the script for me, but I am trying to get better at speaking English, so I am sorry if you struggle understanding me sometimes, but I am not sorry for trying to get better
