For the given code snippet, which among the following options will be printed on the console when executed? ```javascript var arr = ["Violet", "Grey", "Blue"]; (1, 2); (arr); ``` Options: ["Violet", "Grey"] ["Violet"] ["Violet", "Grey", "Blue"] ["Blue"]
Answer (1)
To determine what will be printed on the console from the given JavaScript code snippet, it's important to understand how each part of the code is supposed to function.
The provided code snippet is:
var arr = ["Violet", "Grey", "Blue"]; (1, 2); (arr);
Let's break it down step-by-step:
Variable Declaration and Initialization : The code var arr = ["Violet", "Grey", "Blue"]; creates an array named arr that contains three elements: "Violet", "Grey", and "Blue".
Comma Operator : The line (1, 2); uses the comma operator. In JavaScript, the comma operator evaluates each of its operands (from left to right) and returns the value of the last operand. However, this line doesn't affect the output as it is a standalone expression that doesn't assign its result to a variable or use it in any operation.
Final Expression : The line (arr); simply references the arr array. Parentheses in this context are used to group expressions, but since arr is the only component within the parentheses, this line essentially evaluates to arr and does nothing further.
Putting it all together, since the code doesn’t explicitly include a console.log() or any other output function, nothing is actually printed to the console when it runs. If you intended to print the array, you would need to use a console.log(arr); statement.
Therefore, the correct answer to the question, if meant to understand which array definition is eventually accessed or implied, would be "["Violet", "Grey", "Blue"]" but technically, based on the provided code, nothing is printed to the console.
