Data structures are ways to organize and store data in a computer so that it can be accessed and modified efficiently.
JavaScript provides built-in data structures like arrays, sets, and maps. For other common data structures like stacks, queues, and linked lists, we can implement them ourselves using JavaScript classes.
In this section, we’ll explore:
- Arrays - The most fundamental data structure, storing ordered collections of elements
- Sets - Collections of unique values with no duplicates
- Maps - Key-value pairs where any value can be used as a key
- Stacks - Last In, First Out (LIFO) data structures
- Queues - First In, First Out (FIFO) data structures
- Linked Lists - Sequential data structures where each element points to the next
Understanding these data structures will help you write more efficient code and solve complex programming problems.
