What is the output of the following code snippet?let arr = [1, 2, 3, 4...
Code Explanation:
- The given code snippet declares an array named `arr` with the values `[1, 2, 3, 4, 5]`.
- It then uses the `shift()` method on the array `arr` and logs the returned value to the console using `console.log()`.
Output:
The output of the code snippet is `1`.
Explanation:
- The `shift()` method in JavaScript removes the first element from an array and returns that element.
- In this case, the `shift()` method is called on the `arr` array, which contains the values `[1, 2, 3, 4, 5]`.
- So, the first element of the array is `1`.
- The `shift()` method removes `1` from the array and returns it as the result.
- The returned value (`1`) is then logged to the console using `console.log()`.
Therefore, the output of the code snippet is `1`.
