- Adding Elements: Use
push()to add an item to the end of the array
let fruits = ["apple", "banana"]; fruits.push("orange"); // ["apple", "banana", "orange"]
- Removing Elements: Use
pop()to remove an item from the end
fruits.pop(); // ["apple", "banana"]
- Inserting Elements: Use
splice()to insert elements at any position
fruits.splice(1, 0, "kiwi"); // ["apple", "kiwi", "banana"]
- Extracting Sub-arrays: Use
slice()to create a new array from a part of another array
let citrus = fruits.slice(1); // ["kiwi", "banana"]
- Ease of Use: Compared to other data structures, arrays are simple to create and manipulate.
- Memory Efficiency: They are more space-efficient than structures like linked lists.
- Versatility: Suitable for a wide range of applications, from data storage to complex algorithms.
While arrays are highly versatile, they have some limitations:
- Performance Issues: Accessing elements by index in large arrays can be slower than in some other data structures.
