Events, listeners, promises in javascript (also OOP)

[gmluqa]

For context, just listen to https://youtu.be/gyMwXuJrbJQ?t=48591

If anyone wants to post any resources that explain these concepts really well, please feel free :)))

Personally, it is my first time tackling js front ends and I just want to better understand the whole syntax, what it does, why, etc., if it's too broad of a question please feel free to ignore and I will update this thread with any resources I'm able to find on the topic that may help others in the same situation!

Thank you!!!

Hi @gmluqa ,

For free written information about the requested topics, these are very good sources to look at:

General:

• JavaScript Guide
• The Modern JavaScript Tutorial

Specific to this question:

• Introduction to events
• Promises, async/await

[gmluqa]

Am gonna give these a whirl also, they seem relevant:

On js promises:

On js event listeners:

Thanks for this discussion! Yes, promises are one of the trickier parts of JS... so more resources is good!

Also extending the thread to OOP (in general, not just js but using js as the language to understand it) since I think it's crucial for understanding using interfaces in solidity, object hierarchy, inheritance, etc.. Mainly for anyone in a similar position to me with 'not the best foundations on OOP'.
I am going to give these a look:
