Simulate the arraylist operation in C # using JavaScript (learning and sharing)

Recently, I have been reading JavaScript and learned a lot in Javascript advanced programming. However, I would like to thank Uncle Tom for his selfless dedication in the blog Park. His blog on JavaScript has also helped me a lot. At the same time, I would like to thank "Cai" in the blog, who gave me some suggestions in my essay reply! Thank you again.

 

When I learned C #, I used arraylist. I suddenly wondered if I could use JavaScript to simulate arraylist operations in C! The arraylist instance in C # can be added, removed, and searched later. First of all, it shows that some methods of this simulated operation do not consider execution efficiency issues, but they only report a learning attitude to try.

 

Here to shareCodeWhat's wrong with it. Thank you.

If you have any suggestions to help me improve, I will learn and correct them. I hope to share and learn with you. Thank you.
