JavaScript Data Structures

Advanced Array Operations Sum Up

map() Method

Purpose: Iterates over each element of the original array and applies a specified callback function to produce a new array;
Syntax:

Key Points:
- Does not modify the original array;
- Returns a new array of the same length;
- Useful for transforming each element of an array.

filter() Method

Purpose: Selects elements that meet a particular condition, creating a new array;
Syntax:

Key Points:
- Does not alter the original array;
- Returns a new array containing elements that satisfy the callback condition;
- Provides a way to filter elements based on specific criteria.

find() Method

Purpose: Discovers and retrieves the first matching element in an array;
Syntax:

Key Points:
- Does not alter the original array;
- Halts upon locating the initial match, returning that specific element;
- Returns undefined if no matching element is found.

sort() Method

Purpose: Modifies the original array, arranging its elements in a new order;
Syntax:

Key Points:
- Transforms the original array;
- By default, arranges elements in ascending order;
- Custom sorting can be achieved using a compare function.
