What types of data can JavaScript variables store?

JavaScript is a versatile programming language that allows variables to store a wide range of data types. The correct choice highlights that JavaScript variables can hold strings, numbers, booleans, objects, and arrays.

Strings represent text data, allowing programmers to manipulate textual information. Numbers can denote both integer and floating-point values, facilitating arithmetic operations. Booleans represent true or false values, essential for control flow and decision-making in code. Objects serve as collections of key/value pairs, enabling the aggregation of related data and functions. Additionally, arrays are special types of objects that store ordered lists of items, which can be of any data type, including nested arrays or objects.

This rich diversity in data types enables developers to create complex and dynamic applications, as they can employ the most suitable type for the task at hand, whether it involves simple calculations, managing text inputs, or organizing complex data structures.
