+
+> In this repository you can find classical algorithms and data structures implemented and explained in JavaScript. it can be used as a reference manual where developers can refresh specific topics before an interview or looking for ideas to solve a problem optimally.

+## Features
+
+> Algorithms + Data Structures = Programs.
+
+Algorithms are an essential toolbox for every programmer.
+You usually need them when you have to sort data, search for a value, transform data, scale your code to many users and so on.
+Algorithms are the step you follow to solve a problem while data structures are where you store the data.
+Both combined create programs.
+It's true that most programming languages and libraries provides implementations for basic data structures and algorithms.
+However, to make use of data structures properly, you have to know the tradeoffs so you can choose the best tool for the job.
+That's what you are going to learn here:
+
+- 🛠 Apply strategies to tackle algorithm questions. Never to get stuck again. Ace those interviews!
+- ✂️ Construct efficient algorithms. Learn how to break down problems in manageable pieces.
+- 🧠 Improve your problem-solving skills and become a stronger developer by understanding fundamental computer science concepts.
+- 🤓 Cover essential topics, such as big O time, data structures, and must-know algorithms. Implement 10+ data structures from scratch.
+
+## What's Inside
+
+### 📈 Algorithms Analysis
+
+- Computer Science nuggets without all the mumbo-jumbo.
+- Learn how to compare algorithms using Big O notation.
+- 8 examples to explain with code how to calculate time complexity.
+
+### 🥞 Linear Data Structures
+
+- Understand the ins and outs of the most common data structures.
+- When to use an Array or Linked List. Know the tradeoffs.
+- Build a Stack and a Queue from scratch.
+
+### 🌲 Non-Linear Data Structures
+- Understand how hash maps and sets work.
+- Know the properties of Graphs and Trees.
+- Implement a binary search tree for fast lookups.
+
+### ⚒ Algorithms Techniques
+
+- Never get stuck solving a problem with 7 simple steps.
+- Master the most popular sorting algorithms (mergesort, quicksort, insertion sort, ...)
+- Learn different approaches to solve problems such as divide and conquer, dynamic programming, greedy algorithms, and backtracking.

+## FAQ
+
+<details>
+    <summary>How would I apply these to my day-to-day work?</summary>
+    <p>
+    As a programmer, we have to solve problems every day. If you want to solve problems well, then it's good to
+    know about a broad range of solutions. A lot of times, it's more efficient to learn existing resources than
+    stumble upon the answer yourself. The more tools and practice you have, the better. This book helps you
+    understand the tradeoffs among data structures and reason about algorithms performance.

+    <summary>Hey OP, why you created this repo/book?</summary>
+    <p>
+        There are not many books about Algorithms in JavaScript. This material fills the gap.
+        Also, it's good practice :)
