Look up table is an efficient mechanism by which you can lookup a value that correspondence to a given key. It is faster, simpler, shorter and easily maintainable than using the "if" statement.

Bitmasking is an alternative to lookup table(check previous post), It uses bitwise operations to compare values.
Pros:
It is faster than lookup table because it uses bitwise operation rather than the .includes method used by lookup tables.
Cons:
You have to understand bitwise operations in order to understand it.

you can read more about bitwise operations here:

The debounce function is similar to throttle, it delays the processing of an event until the event has stopped being called for a predetermined amount of time.

Usage:
* Have you noticed that when you type into a search input, there will be a delay before the typeahead results appear. This functionality is frequently controlled by debounce.

Advantage:
* It prevents your code from needing to process every event thus improve performance.

My advice, if you are going to be having conflicting styles for a single element, make sure to use the same style declaration for all conflicts, that's better than putting "!important" all over your code or changing your code order.
