Which statement is true about JavaScript arrays?

Question

Options

• AArrays in JavaScript can only store elements of the same type.
• BArrays are used to store multiple values in a single variable.
• CArrays in JavaScript are fixed in size once declared.
• DJavaScript does not support array methods like push() or pop().

• A
  4% (2)
• B
  94% (48)
• D
  2% (1)

Explanation

JavaScript arrays are designed to store multiple values in a single variable, making B correct - you can collect items like names, numbers, or objects all under one identifier (e.g., const items = [1, "hello", true]). A is wrong because JavaScript arrays are dynamically typed and can hold mixed types in the same array. C is wrong because JavaScript arrays are dynamic in size - you can add or remove elements at any time without declaring a size upfront. D is wrong because JavaScript has a rich set of built-in array methods including push(), pop(), map(), filter(), and many more.

Memory tip: Think of a JavaScript array as a flexible shopping bag - it can hold anything (any type), you can always add more items or remove them (dynamic size), and it comes with built-in tools to manage what's inside (array methods).
