What is the syntax for creating a JavaScript array?

The correct choice for creating a JavaScript array is represented by the syntax: var colors = ["red", "green", "blue"];. This approach utilizes the array literal syntax, which is a straightforward and efficient way to initialize an array with specific elements directly within square brackets. This method is commonly used because it is concise and easy to read.

Using the array literal syntax also allows for the immediate creation of an array with predefined values, which is a common practice in JavaScript programming. The values placed within the square brackets can be of any type, including strings, numbers, and even other arrays.

The other choices presented do not align with standard JavaScript array creation practices. The first choice, while valid, utilizes the new Array() constructor, which is less commonly used and can lead to confusion, especially when creating arrays with a single numeric argument. The third choice is incorrectly attempting to create an array using a function-like call, which is not valid syntax. The fourth choice uses parentheses instead of brackets, which does not conform to any valid array creation method in JavaScript. Thus, the array literal form is not only the simplest but also the most widely accepted way to define an array in JavaScript.
