What is the most common error you see people doing over and over? Maybe some common wrong belief?

I think the 2 most common errors in JS, are mostly:

Trying to access any property into an undefined or null.
Trying to invoke an attribute as a function, this can relate with the first point, anyhow I saw this too much.

In the management side:

Not hear the people, it can be someone is about to leave the project/company.
Not hear the recommendations before taking a poor technical decision.

In general:

Over-optimize everything without setting the proper metrics.
Keep technical debt growing.
Set everything as an urgent requirement.

True: when everything is a priority, there is no prioritisation.

Cutting quality helps to meet a deadline.

Thinking that something is "simple", or even worse: "easy".

And once they have been burned enough by this error they will blow everything out of proportion, which generally leads to a downward spiral of diminished returns.

At the language level : Variable length Indexed Lists are the only collection you need. Arrays, Sets, Hashtables, Dictionaries, Linked Lists, and others all are better solutions for some problems.
