September 11, 2024 - In this article I'll try to give a simple explanation of data structures, what they are, when are they useful, and how we can implement them using JavaScript.

Programming languages all have built-in data structures, but these often differ from one language to another. This article attempts to list the built-in data structures available in JavaScript and what properties they have. These can be used to build other data structures.

JavaScript data structures help to manage and manipulate data in JavaScript programs. Here's 8 common JavaScript data structures to know, with sample code.

This repository contains JavaScript based examples of many popular algorithms and data structures.

February 5, 2025 - A hash table is a data structure similar to objects — a collection of key-value pairs. In Javascript, it’s often named an associative array. A hash table secretly transforms the key-value into a number (aka a hash) with a so-called hash function.

Never seen a linked list in frontend JavaScript code? Me neither. But here are real-world examples of data structures Map, Set, Stack, Queue, and Tree.

May 14, 2021 - Arrays are the most basic data structure. It is a group of similar types of elements stored together at contiguous memory locations and each cell has a corresponding numeric index used to select its data. Like all scripting languages​​, JavaScript has dynamic arrays i.e their size is not predetermined, nor the type of data. An array literal is the easiest way to create a JavaScript Array. Let's see the simple example of creating an array using an array literal:-

October 10, 2025 - This beginner-friendly guide covers Data Structures and Algorithms (DSA) in JavaScript, including built-in structures like arrays, strings, Map, Set, and user-defined structures such as linked lists, stacks, queues, trees, heaps, and graphs.

A binary search tree is a hierarchical data structure of ordered nodes with at most two children each. ... Learn how to build an undirected tree from an array of edges in JavaScript, with various approaches for storing node relationships.

January 26, 2025 - Data structures are formats in Javascript that help access the data in more efficient ways. In this article, we will discuss some common types of data Structures used in javascript. Click here to know more.

June 4, 2024 - The back button in web browsers is a good example: each page you view is added to the stack, and when you click back, the current page (the last one added) is popped from the stack.

The first thing he needs is a data structure to store this information. To work with a chunk of digital data, we first have to find a way to represent it in our machine’s memory. Say, for example, that we want to represent a collection of the numbers 2, 3, 5, 7, and 11.

February 17, 2021 - Static data structures have a fixed memory size, that is, you need to state the maximum size of the structure well in advance. We cannot allocate the memory later. The example of static data structure is arrays. We learned about them in the DataFlair’s previous tutorial on JavaScript Arrays.

October 16, 2023 - Here are some common javascript data structures available: Arrays: Arrays in JavaScript are ordered collections of elements that can hold values of any data type. They are indexed starting from 0 and can be dynamically resized. Arrays offer various methods for adding, removing, and manipulating elements. Example:
