In this post, we’ll break down the most essential methods into clear categories:
- Adding & Removing Elements (e.g.,
push,pop,splice) - Iterating & Transforming (e.g.,
map,filter,reduce) - Searching & Finding (e.g.,
find,includes) - Slicing & Joining (e.g.,
slice,concat) - Ordering & Testing (e.g.,
sort,every)
Let’s dive in and visualize how these methods actually work under the hood.
