## Dynamic Arrays

A dynamic array is a data structure that can grow or shrink in size during the execution of a smart contract. Unlike fixed-size arrays, dynamic arrays provide flexibility for handling variable amounts of data, such as a list of users or a history of transactions.

In smart contracts, dynamic arrays are stored in storage and can be modified using push and pop operations. While they are convenient, they can be gas-intensive because adding elements may require reallocating storage or updating multiple slots.

Developers must be cautious when using dynamic arrays in loops, as the gas cost can increase linearly with the size of the array, potentially hitting block gas limits. They are best used when the size of the data is unpredictable or when flexibility is required.

Effective management of dynamic arrays is key to building robust and scalable smart contracts.
