Javascript algorythm and data structure for beginner
Data Structures are ways to organize and store data so it can be accessed and modified efficiently. Algorithms are step-by-step instructions (logic) to solve problems, like searching, sorting, or manipulating data. These are core skills for every developer, especially useful in coding interviews, app development, and problem-solving.
Arrays are ordered collections of data, like a list of items. They’re useful when you need to store multiple values in one place and access them using index numbers. Objects store data in key-value pairs and are great for representing real-world entities like users, products, or settings. Stacks work on the principle of Last-In-First-Out (LIFO). Imagine a stack of plates — the last one you put on is the first one you take off. Queues follow First-In-First-Out (FIFO) — like people standing in a line. The first person who enters the line is the first to be served. Sets store unique values and are useful for removing duplicates from an array or checking if an item exists. Maps allow you to store key-value pairs like objects, but with better performance and more flexible key types (not just strings).
