Which term refers to a data structure used to represent a list in JavaScript?

• A. For Loop
• B. Parameter
• C. Array
• D. Bit

Answer: (C)

An array is a data structure used to hold a list of values in JavaScript. It stores items in a specific order, and you can access each item by its position, called an index, starting at 0 (for example, array[0] is the first item). This makes arrays ideal for representing lists, like items to buy or a sequence of numbers. You create one with square brackets, such as let items = ['apple', 'banana', 'orange']; and you can grow or shrink it with operations like push to add or pop to remove, while the length property tells you how many items are in the list. Arrays are versatile and can hold different types of values, even mixed types, which is handy when you’re storing a collection of related data points.

The other terms refer to different concepts: a for loop is a way to repeat code, not a container for values; a parameter is a variable that a function uses to receive input; a bit is just a single binary digit (0 or 1).
