Array vs objects in javascript

Arrays in JavaScript

Definition:
Arrays are ordered collections of items.
Each item in an array has an index, starting from 0.

Key Points:
Mutable: Items can be added, removed, or changed.
Indexed Access: Access items using their index, e.g., array[0] for the first item.
Methods: Common operations include adding (push), removing (pop), filtering (filter), transforming (map), and reducing (reduce) elements.

Objects in JavaScript

Definition:
Objects are collections of key-value pairs.
Keys (properties) are strings (or Symbols), and values can be any type.

Key Points:
Dynamic: Properties can be added, modified, or deleted.

Comparison
Arrays: Best for ordered collections and list-like structures.
Objects: Best for key-value mappings and representing structured data.
Arrays and objects are fundamental data structures in JavaScript, each serving distinct purposes in organizing and manipulating data.

Yo le pondría stickers con Uhu al que pegó tonterías al pobre minino, en dónde más le duela para que cuando se los jale, recuerde la cara del michito.
