Overview

This cop checks that the closing brace in an array literal is either on the same line as the last array element or on a new line.

When using the `symmetrical` (default) style:

If an array's opening brace is on the same line as the first element of the array, then the closing brace should be on the same line as the last element of the array.

If an array's opening brace is on the line above the first element of the array, then the closing brace should be on the line below the last element of the array.

When using the `new_line` style:

The closing brace of a multi-line array literal must be on the line after the last element of the array.

When using the `same_line` style:

The closing brace of a multi-line array literal must be on the same line as the last element of the array.

Examples:
